Improving Sound Since 1998

I live in UK and I bought a Boostaroo amp several years ago. I loved it. It circumvented the European Union "nanny state" recommended maximum headphone volume rubbish. It powered my Sennheiser noise reducing headphones for ages on one tiny AAA cell. It went with me all over the world. Imagine my distress when it was stolen from my rucksack in the British Museum in London. I was very sad. Guess what - I emailed Boostaroo in the US, and told them my tale. They responded immediately and dispatched a (newer) replacement amp to me at my son's address in New York. Thank you Boostaroo - brilliant service.

I'm in the process of ordering my fifth amplifier, the sound enhancement is Incredible but they only last me maybe a good six to seven months.Before the cord slices and I loose one side of the volume. I have never sent it back to have it replaced but this time I will. Again GREAT SOUND.

I just received the Boostaroo Revolution Black Friday Bundle and let me tell you,this marvel not only boosts volume but the Audio Cross Feed Circuit really enhances the audio signal to make it sound like you are actually in front of the performer! And made in the U.S.A.! This is the best device of it's kind at any price! Thank You.

Awesome service, I had no problem aquiring much after sales service after buying online and I live on the other side of the world, I found the staff very helpful and eager to satisfy my curiousity in many things.

Got my Boostaroo and hooked up to my satalite radio on my Harley using earbuds. Had to add a volume control it boasted the sound a little more than I wanted. But great product. I can control the sound and hear my music on a trip with no problem. I had purchased speakers in the past but alwasy had problems and they did not last. Love the Boastaroo.

I used the Boostaroo Revolution this past weekend in the car while listening to my favorite songs on Pandora. The amp was connected between the aux input and my smart phone. The sound enhancement was great and it made the long road trip a very enjoyable listening experience.

I just received the on-special $19.99 Boosteroo amplifier and headphone package, plugged it into my amateur radio transceiver and I'm very pleased with the results. In ham radio, there are small transceivers with minimal audio output and in noisy locations we usually wear headphones, so this was an easy, convenient conversion. The audio gain is impressive. The build quality and features are better than I expected and I can highly recommend Upbeat Audio for quick handling (thanks, Laura). -K6PJV

I use the Boostaroo at work and at home. I use it all the time and I absolutely love it. I highly recommend it!

I recently ordered the Portable Audio Amplifier and Headphone Bundle T613-DN. I planned to use it with my cell phone on conference calls with my company's home office. From my original phone call to UpBeat Audio to ask about the product through the several times I've used the product, I have only positive things to say. My phone call was answered on the first ring by a real person, and my question was answered by a friendly and competent person. The product was delivered to my home only a couple of days after I ordered it, and the set-up was easy. Now I can hear everything in the conference calls (the inline volume control is really handy), and I also use the unit with my laptop to listen to online radio at the local coffee shop (like at this very moment). The price is reasonable, as was the shipping charge. I am not a tech person and am usually skeptical of most gadgets, but I am sold on this device. It is refreshing to have such a positive experience--I would recommend this device and this company to anyone!

I bought Boostaroo few months ago, and I can say that it's an excellent product.
I love it!!!

Es un excelente producto. Lo recomiendo totalmente!!!

June 1, 2013 Brian Quist

I bought 2 of these thinking they would increase the volume of our I-pods on our motorcycles. There was no appreciable increase. I did not see any improvement in using the Boostaroo. I no longer use mine.

May 28, 2013 Carl Scarlett

I love my Boostaroo. Being a regular listener of music and podcasts on public transport, I was frequently losing the battle against background noise (despite having a set of awesome headphones). With my Boostaroo plugged in I can ramp up the volume to ear-bleeding levels if I like, but often only have to listen at half volume.
The only downsides are the cable ports are getting a bit loose after years of plugging and unplugging, and I'm losing sound sometimes (one or two stereo channels) if the cable gets pressure on it. Also, the power indicator doesn't help me to identify that the batteries are going flat, so I tend not to notice the sound quality dying off until I listen to a high quality track.

May 28, 2013 Bill

Boostaroo is the bomb! I like the model that allows me to hook it up directly to the battery on my motorcycle. No more changing batteries! And it works like a champ with my XM radio!

May 27, 2013 Ian James

I purchased a Boostaroo amplifier for my motorcycle satnav / MP3 player in order to increase the volume. I had suffered for four years not being able to hear my music or satnav directions clearly enough. I installed the Boostaroo amplifier and this made an immediate difference. I can now hear my music and satnav instructions clearly. I now have to turn down the volume such is the difference Boostaroo made on my listening experience. Keep up the good work.

May 27, 2013 Anita Harrison

I use the Boostaroo in Sound therapy (Filtered Sound Training, FST) because it's important for the success of the therapy to have the music loud enough - up to 80 or 85 dBs. Without the Boostaroo it is impossible to attain the desired dB levels. So the Boostaroo is an essential part of the equipment in FST. I am indeed very satisfied with the performance of the Boostaroo Revolution and the fact that it's so compact,yet powerful. As the official trainer in Canada and the USA for FST, I make sure all the Practitioners use the Boostaroo Revolution and have also recommend it to the head office in England, who is now also using it.

May 25, 2013 Richard Rosecky

I have owned my "boosteroo" for about two months. It works just fine. I bought it because my somewhat old pc did not boost audio volumes sufficiently for me. I use boosteroo to amplify the audio volume. It is not a large boost, but it is sufficient.

May 25, 2013 Alex Gonzales

I love my boostaroo amp, mostly when on the tractor I can hear the music and don't have to guess whats playing.

May 25, 2013 Lee Smith

the item was easy to order. Arrived fast,well packed. Works great. I am happy with the whole experience. Ill be back for more!

May 24, 2013 Martha Sheil

Although it did boost the sound, it was still not enough for my project
because it also boosts the ambient noise.But my recording was very poor

May 24, 2013 C Reilly

Since I have been using this for my work as a transcriber, it has improved the sound more clear and louder. I really love it except for the battery having to be changed out often. Great product

May 24, 2013 Pieter Blom

I'm learning to fly and as part of this i bought a good quality headset, which worked perfectly in one aircraft but was not useable in the other, which I normally use, due to an impedance mismatch. The headphone supplier said there was nothing to be done other than to replace it.
Luckily I found Boostaroo on the internet. The combination of your amplifier and my headset allows me to hear perfectly.
Thank you.

May 24, 2013 Mark

I purchased a regular USB powered boostaroo a while back . I used it for about 2 years and thought it was an excellent product. It did a great job of amplifying the on-board sound of my PC with no distortion and driving my headphones properly.

Since then I moved on to a more expensive DAC but I still fully recommend the boostaroo as an inexpensive solution.

May 23, 2013 Howard

My Boostaroo has performed flawlessly. Easy to install & operate. No way to do it wrong, that easy. Highly recommend Boostaroo for anyone with issues of insufficient volume for whatever device they are using.

Nuff' said...

I use the 12v powered amp on my GPS audio to feed the Aux input on my 2009 Harley-Davidson Ultra Classic. Without the amp, my headset volume was set at 100% and still it wasn't loud enough to hear. Now the volume is set at about 50% and there's plenty of sound. The quality of the audio is pretty good but with helmet headsets, great ain't gonna happen. The install was easy and the amp was small enough to tuck back into the rat's nest in my fairing. I enjoy my mp3 tunes much more now.

May 23, 2013 Bojack

Don't spend all your money on high dollar amps that are just space age and trendy. Boostaroo WORKS!!! I'm from the 60's so I like it simple and complete.
I use my V-Moda Crossfade LP headphones and the Boostaroo and that's it.
It's clean when the music calls for clean and down right combustable when the music calls for it. Do yourself a favor, get a Boostaroo...These folks know what they'er doing.

May 23, 2013 Juice Pod

Hello Boostaroo,

I love the audio amplifier. I have a meetup group and we need to amp up the power to 10 headphones so we can all listen at once to a audio track and this does the job beautifully.

I have been using the Boostaroo audio amplifier for years with my netbook and now tablet. When traveling and wanting to use two headphones with the netbook/tablet I would not be able to hear anything without Boostaroo amplifer. The amplifer provides the boost in volume which is needed.

Great product and has worked great without any problems.

May 23, 2013 Michael Moreno

I loved my Boostaroo while it lasted. I got about 6 months out of it then it died, nothing but static noise comes through it and no it's not the batteries.
But while it lasted it was awesome, helps you hear more detail in your music helps your PMP batteries last longer, it's a great idea but I just wish it was made with a little better quality.
The quality is the only real Con about this product, buyer beware, you might get one that last a decade or a month.

May 23, 2013 Bob

I have owned two battery powered units and one 12V powered unit. I am very disappointed in the performance of the 12V unit as it's power output is low and only one channel(speaker)seems to work.

May 23, 2013 Stuart

1st one stopped working. I think it was due tote cable being bent perhaps
2nd one stopped working properly as well. I think something inside is loose

May 23, 2013 Wayne McIver

I have suffered hearing loss for a number of years and decided to purchase the R234 amplifier which I connected to my IPOD and more recently, my cell phone. Absolutely brillant. I can hear all my muisc clearly on the train,etc. Best thing I ever did. Thanks Boostaroo. Wayne

May 23, 2013 Stefan Ljungqvist

I am a very satisfied customer.

May 23, 2013 Martin

Connected this device between my samsung galaxy note and AUX on my car stereo. Pretty disapointed, the differance is hardly hearble.

May 23, 2013 Bill

I've had my boostaro now for over a year and use it with my Hendricks QRP Ham Radio PFR-3A when signals are down and the radio doesn't have enough audio by itself. The little bit of audio gain makes the difference between hearing a signal and not being able to copy that signal well enough. Very good product for the price.


May 23, 2013 John

I now own three Boostaroo amps. One for my laptop/phone/whatever with headphones, and two of the 12v powered amps mounted on my motorcycle to boost the sound of my Garmin on the way to my helmet speakers. Hey, there's a LOT of wind noise to overcome when you ride like I do. ;) The amps work GREAT!! I can't imagine listening to music without them. GREAT products Boostaroo!

May 23, 2013 Dan

The Boosteroo provided an easy solution to a persistent and annoying problem: achieving sufficient volume from the MP3 player plugged into the auxiliary input of a 2008 Subaru sound system. Not only does it provide sufficient amplification, but the batteries seem to last for ever, or at least through several audio books

May 23, 2013 Bbecky

I am surprised at how simple the Boosteroo is, yet how great it works. I'm a MT student and the Boosteroo allows me to turn down the volume on the dictations thus reducing static and feedback. The clarity of the dictations has greatly improved thanks to the Boosteroo. I use an extension speaker wire to place the Boosteroo in an easy to reach location. Every day when I'm done transcribing I unplug my Boosteroo from the computer in order to prolong battery life. I read that the battery last 40 hours (1 work week), but by unplugging at night I have used the same battery for months.

May 23, 2013 Todd

Awesome little product. I used it for a TV in my bathroom that didn't have much volume upside. Gives me a ton more range.

May 23, 2013 Melissa

Great product. This product helped to boost my audio so much. It's awesome.

May 23, 2013 Glady Tucker

Can't call this a testimonial. I ordered the Boostaroo, and it didn't work. Talked to your tech and they said to send it back. I did. They promptly sent me another one. It didn't work either. So I sent that one back and was promptly credited for it.

I would love to be able to use the Boostaroo but for some reason they don't work.

May 23, 2013 John Caulfield

I use it on my Ipod nano and I'm very happy with the boost in volume. It really enhances the sound coming out of my Bose headphones.

May 23, 2013 jason

Been using it for a while now on my motorcycle. I run XM radio and it is very quiet. I get just the right boost from this unit. Only thing i wish was different was that there was a switch to turn it on and off vs unplugging and that it used a standard battery. Otherwise i love it.

May 23, 2013 Tylor Heath

My product is not what I thought it was going to be its not quite what I need I need a bigger and better one for what I use it for.

May 23, 2013 Steve

Could not live without my Boostaroo. The sound coming out of my laptop and my tablet on cross country plane flight was inadequate and made trying to enjoy my media thoroughly frustrating. The Boostaroo truly boosted the sound significantly making listening to all my media on flights 100% more enjoyable. Sound quality is good as well. Highly recommend the Boostaroo!

May 23, 2013 Cliff Diable

I own 4 boosteroo amps...for different uses (2 computers, 1 TV and 1 for my cell phone). Being very hard of hearing and using a hearing aid, my boosteroo squad has brought me back into the "hearing world". What a blessing... I love 'em!!

My next purchase will be a back-up in case one amp needs service--not that any ever have. No one problem in 4 years.

Keep doing what you're doing and THANK you!

Cliff Diable

May 23, 2013 Jon radeck

Awesome product, what a diference, brings a whole new experience in headphone listening, oh and the staff is GREAT! Keep up the good work!

May 23, 2013 Dee Snyder

The Boosteroo has been working GREAT!! It greatly enhanced the volume of the dictators, many of whom I could barely hear before. I am SO GLAD I purchased this item.

May 23, 2013 JTKirb

I use Westone music earplugs on my motorcycle which provide 15db of noise reduction across the frequency spectrum. My music player has trouble boosting volume enough to hear with the earplugs in. The Boostaroo revolution provides enough boost to hear my music while knocking down fatigue inducing wind/road noise with my ear plugs. Highly recommended.

May 23, 2013 G Calise

My Boostaroo did improve the sound quality and overall volume of the music I listen to...making the experience much better for me. My unit did not last long before malfunction and failure. Also, the extension wire freyed at the connector a short time after purchase. This product cost less than any alternative I found and was great while it worked.

May 23, 2013 Randi

Ordering was a little challenging from the Website, so I phoned in my order. The customer sales rep was knowledgeable and friendly. I received my order in 2 to 3 days' time. This is the second Boostaroo-UpBeat Audio headphone set I've purchased. Loved my first set so much that I bought a second one. The headphones are the absolute best, and I own at least a half dozen other headsets. Love that I can adjust the volume.

May 23, 2013 fabio

My Boostaroo is OK, except for the interference and background noise.

Best regards,
Fabio De Santis.

March 11, 2013 Michaelyn

The Boostaroo amplifier arrived this afternoon. I set it up, put in David Sanborn's "Hideaway" (which I could barely hear before) and it is LOUD and clear; I am laughing and almost crying. Put in audio book disc I could not understand before and now I CAN! Just wanted you to know!

March 6, 2013 Marie7

I had read great things about the Boostaroo and was so excited to get mine! Sadly, it doesn't seem to work...when I plug it in, I actually LOSE's been worthless for me...such a waste of money. :(

January 28, 2013 Eric Gordon

I just purchased the R234. I love it. The quality is really good and it's crisp and loud. Thank you.

January 3, 2013 Griffin Haskins

I stumbled upon this site almost 8 months ago. I decided to try the monthly drawing and thought, "what have I got to lose?" A few weeks later, I won! I was very excited; I got my amplifier just a few days after. I tried the amp and I was simply amazed at how loud it could get! It may sound rather... rehearsed but, honestly, I would recommend this to a lot of my friends and family. Trust me, you will like it.

December 28, 2012 Kevin

I love your product. I have had it for nearly a year and go nowhere without it. I can watch TV in hotels, listen to a mp3 player, and hear my computer. This is the best invention.

December 26, 2012 Jim (Scotland)

This product is truly amazing! Their customer service is second to none. I had a delivery problem, they sorted it out straight away and I received my Boostaroo in only 6 days!

December 21, 2012 Antonio Baird

I received one of your company's boosters and was blown away. Thanks for supporting America's Soldiers. I was able to listen to my headset on a C17 Aircraft and hear the music. It's a great device.

December 19, 2012 Fergus Massey

So impressed was I by the Boostaroo, I bought a second one soon after my first just in case my first one broke; it didn't. Before I forget I should review the Boostaroos ability to amplify the audio played through it. For that I give it top marks, actually improving the sound quality of music while increasing its volume. Some things in life are just brilliant, take a bow Boostaroo!

December 18, 2012 Boydine Boatwright

I have a profound hearing loss and finding a MP3 player that is loud enough for me to hear was a hit or miss. I can't tell you how many MP3 players I have bought and had to return because I could not hear the music on them. Even the cool MP3 players like the ZUNE, and IPODS. I bought the Boostaroo thinking that it was going to amplify the sound enough for me to hear. I was thinking that I would have to return it, but I was wrong. THIS ROCKS!!! Trust me, it is worth the money. It is nothing compared to what I have sent in the past! So, take it from the deaf guy. If I can hear with it, then so will people looking for that extra boost of volume to hear the music over machines at work or just loud surroundings. You will not be disappointed with this amplifier! This thing worth its weight in gold!!!

December 6, 2012 William F. Jakobi

This is an AWESOME Product! I have used the Headphone Amplifiers for 2 years now and they work great! My music is much more clear, full and real sounding now. Plus, the bass is excellent and the high treble is superb. I use them with Koss headphones in the Gym and I couldn't be more pleased and happier with this great invention. Plus, the battery has literally lasted me over a year in both amplifiers. I just make sure to unplug the Input Cord when I am not using it, so that turns OFF the Boostaroo. Thank you for a GREAT PRODUCT!

December 4, 2012 Steve S.

My Boostaroo is fantastic! I use it at least twice daily in my car, boosting my MP3 player through my car stereo.

December 3, 2012 Chris E.

Just to let you know it arrived yesterday and I'm very pleased with its performance.

November 30, 2012 Stephen S.

I just got a R234 for use on my motorcycle. I use it for my satellite and mp3 in conjunction with the bike radio input. WOW...FANTASTIC.

November 28, 2012 Randa

I just have to tell you, after I adjusted all of the connections and put my new headsets on with the Boostaroo Revolution, I started listening to Luis Miguel and he may as well have been sitting right next to me with a full orchestra! Your products are FABULOUS and I have never been so pleased with any purchase in the way that I am thrilled over this one.

It is such a pleasure to experience a customer service level and product offering that your company provides. It has been literally decades since I have had the privilege to buy a product at a very fair and reasonable price, and have it perform at the 10-star level that this does. But on top of all of that, to have a real person at the other end of the line who not only knows their product line and how it works, but also has the congeniality and graciousness that I have found in contacting your firm, makes me believe that there is still hope for the USA and the the good old-fashioned pride in America. So thanks again for the inspiration, the great products, and the kindness that is rarely experienced in this new millenium.

November 26, 2012 Pat

I wasn't expecting much from a gadget but I'm pleasantly surprised! I just needed a little more volume and didn't want to invest in a huge receiver. This is a great solution.

November 25, 2012 Devan Dixon

This product is revolutionary! (just like how they've labeled it) Trust me its unbelieveable - I now have to turn my iPod down for fear of popping those eardrums. You will not be disappointed. Its money well spent for music lovers on the go.

November 23, 2012 Todd

Best money ever spent. I purchased a garmin for my car for gps and mp3 purposes, but the volume output from my garmin into my car's aux input was just missing that "extra punch". I'm sure garmin does this in order to save on the battery life if running off batteries.I was even considering about dropping well over 300 dollars for an amp and new speakers but I really didn't want a huge "bumpin system" as I'm getting older and I just don't care about such things anymore and there is really nothing wrong with my stock stereo system when listening to the radio or CD. All I wanted was more volume from my garmin and hopefully with no distortion or static. I ran across this usb connected boostaroo and after reading some reviews I said what the hell and I'll give it a try. I plugged the usb adaptor into my cigarette lighter and powered on the usb connected boostaroo (which you can keep the power button on so it starts up with the car ignition, tucked everything up under the dash, and turned on my stereo system. All I can say is WOW! Where I had to turn up my car stereo to 75% is now @ 40% easy. No distortion, no static. Bass and overall sound was very very impressive. I seriously think the bass "sounded" better also. I even put my garmin on pause, cranked the volume to listen for static... NONE. I'm very impressed. Now I have all my electronics radar detector, garmin, and my boostaroo all powering up with my car's ignition thru a 3-way cigarette lighter splitter... all tucked up behind dash... you don't even see any wires nor the boostaroo. This little headphone amp gave me the extra punch/edge I was looking for with out spending big time bucks on a whole new system. Thanks big time!

November 21, 2012 Paolo Gosio

My Boostaroo works great, and I always have it with me during my frequent intercontinental flights, on which I need to amplify the volume of my headphones to compensate for the noise of the plane.

November 20, 2012 Kevin Kinzer

Wow, I was having such a busy time here, I didn't let you guys know how great your product was received here. I kept one, and used it mostly on my laptop, which doesn't output a lot of volume anyway. It worked absolutely fantastic! The Boostaroo Revolutions that I passed out to the guys here were used on convoys throughout Iraq, and were amazing! They were able to drown out the noise of the vehicles, which is unbearable at times. Thank You so very much for your great product. There are some happy people here because of your dedication to the soldiers here. Thanks Again Kevin Kinzer Task Force 293rd

November 19, 2012 Steve Kayatin

I use the revolution as a preamplifier to my amplifier for my motorcycle speakers using an mp3 player for the source. The revolution has at least doubled if not tripled the power coming from my mp3 player to the main system amplifier.

November 14, 2012 Bob S.

I love this little Amp! Get One!

November 13, 2012 Frank Wahl

I received my Boostaroo today. WOW!!! what a tremendous difference, and w/no distortion. What a great product, I will recommend to all of my friends.

November 9, 2012 George


November 1, 2012 Matt T.

We used our Boostaroo on our recent trip which included 4 different 15 hour drive days. It worked flawlessly and I heard no complaints from the kids about not being able to hear the movies. Thanks!

October 30, 2012 David Harris

I bought the Boostaroo Revolution for my Archos. The Archos has absolutely horrible volume, I could barely hear it. When I hooked up the Revolution it was like a completely different player, it sounds amazing now.

October 25, 2012 Murray

Love ur tunes when unchained to your desktop? Gott'a getcha one of these. They make a dramatic improvement. Easily slips in my pocket too. Miss out if you want to. Im Rockin'.

October 22, 2012 XxBravadoxX

I just purchased a quality mp3 player and top of the line in-ear headphones a few days ago. I was happy with the audio quality but the volume was very disappointing. I searched and found out that a headphone amp was made a mad dash for a local retailer who carried the Boostaroo. WOW!!! Now I got some punch in my tunes. Great product!

October 17, 2012 Larry F.


October 16, 2012 Brian Cassani

I hope you enjoy the Boostaroo as much as I have! This is my third purchase from this company, and I cannot tell you how much I love these things. They turn your Mp3 player into a powerhouse of sound that can be heard by people standing next to you even with your cheapest headphones on!

October 12, 2012 Charlie Montgomery

I was pleasantly surprised, by the increase in sound! My mp3 player is now, more than loud enough, with NO hissing or distortion. I just wanted to say thanks for all your help, and I can say that I'm a happy customer!

October 10, 2012 Kerry Kist

Wow, received my Revolution in less than 1 week. AMAZING sound! What a GREAT product. Now I can hear music like it was meant to be heard through my iPod! I will recommend this product to everyone. Thankyou, Thankyou Thankyou!

October 8, 2012 Helen Holmes

I am 65 years old and because of genetic nerve deafness which showed up over 20 years ago and has now left me with 8% hearing in one ear, I was desperate when I ordered your Revolution: I hadn't heard music harmony in years and all of a sudden I could. I have very expensive digital hearing aids that barely let me get by. And I sit here and look at your product as bringing the horrendous cost of less effective digital aids to the many elderly and poor of this nation who often are left with nothing. Yours is the ONLY product that has let me rejoin the human race! Many thanks.

October 4, 2012 Mark Britton

Just wanted to say thank you for the great customer service. My son and I both use our Boostaroo's with MP3 players and the Aux input on the car stereo. Works fantastic!

October 3, 2012 Lee Smith

Just a note to say we love the amplifier!(and 1/6 the price of TV EARS) The whole purchase experience was great! We will do business again.

October 1, 2012 Danny Philips

I discovered Boostaroo and it was like magic - music was a joy again. I am inspired by the improved quality of sound that reaches my ears. Bless the Boostaroo for making performing a pleasure again.

September 28, 2012 Glenn Kelly

Just received my Revolution. It's absolutely what I was looking for - anyone who is frustrated by the sound caps on European bought iPods should get one! Great customer service, too! Will be recommending to anyone who will listen!

September 25, 2012 Willie Bryson

I bought the Boostaroo and I didn't believe that it could do what it said it would. But now I'm convinced, since I hooked it up to my new Bose Portable Sound System and my cell phone. It is fantastic, and sounds incredible.

September 24, 2012 Eric Ocean

I just wanted to let you know how happy I am with my Boostaroo. I bought a smartphone that is advertised as a "media" phone and it is crazy how low the volume is on it - with every setting on high. Well I got the original Boostaroo and now I keep my device volume at around 70% - instead of 100% - and I am astounded at the volume level and sound quality. It's just simply awesome. As soon as I upgrade my earphones I will definitely be upgrading my Boostaroo to the Revolution model. Thanks for a great product.

September 21, 2012 William Heidelberg

Just got that Boostaroo unit with ac plug-in and it got my PC volume back. Wonderful product, worth every penny I spent.

September 18, 2012 Michael Smith

I've had a couple of these units over the past several years (I think they get swiped when folks see it!) Now I need another! At any rate- very handy, blast the music over the road noise/jetnoise/screamin'-baby noise... whatever. Super product!

September 13, 2012 Scott P Gregg

Just got my Revolution® Series USB Powered Audio Amplifier and Splitter . OUTSTANDING! Works as stated. 2 day shipping :-)
Maverick and Charlie Girl (my cats) are running for cover.

September 7, 2012 Lisa

W O W! I just received my Boostaroo Revolution, no kidding, that thing is GREAT! I am very pleased with this purchase. Thanks guys for the great product! My mp3s sound so much cooler now.

August 22, 2012 John Tobias

I just received my Boostaroo Revolution today. It is nothing short of spectacular. I just love it. It was easy to splice into my satellite radio on my motorcycle and it is so loud I can hardly turn it up. the best money I've ever spent.

I finally found the headphones that when combined with your revolution, gives tremendous sound quality. Next step would be to create an amplifier that is small and rechargeable and less cumbersome, which looks like part of the headphone itself. Another idea would be to create a mp3 player where the amplifier is built in. WOW!

I bought the Original Boostaroo about six months ago so I could take advantage of the aux. input on my car stereo deck. I couldn't believe how loud it got. But recently I've been feeling the need to go louder, so I bought the Revolution. I could not turn my stereo all the way up since it was so loud. I have aftermarket speakers also, so the sound quality was amazing, a huge difference between the original and the revolution.

August 16, 2012 Rebecca Williams

I transcribe medical reports. This is the first time in my life that I have not had to have the computer volume control all the way up plus the speaker volume up half way. Now, I have the PC volume only 1/4 the way up! THANK YOU FOR A PRODUCT THAT WORKS.

August 14, 2012 Dave Adkins

Just a word of thanks to all of you at Boostaroo. I purchased my first one ages ago to improve the volume output of my iPod. Only recently did the male connector develop a short - a result of my not so delicate handling and the wear and tear of several years of constant traveling. I'm elated and amazed it lasted as long as it did. At any rate, I just ordered a new Revolution and literally can't wait for it to get here. I remain one of your humble fans.

August 8, 2012 Will Cage

Wow you guys are fantastic kudos for customer service. Oh yeah the amp is making my iPod sound soooooooooooo much better. Thank you! Happy Boostaroo freak Will Cage

August 2, 2012 Bill Bryant

Just wanted to let you know that I received my Boostaroo several days ago, tonight was the first opportunity to try it out. I have hooked it up with a set of speakers and my digital projector. The sound was terrific, my grandson now wants to have Mondays as movie night at our house. You have a great product, that has surpassed my expectations. I will be using it soon in a classroom setting where the sound will be a great help.

July 30, 2012 Mark Steffens

I just ordered two of these. I have been using one with my MP3 player when I ride my motorcycle for about three years. Finally my son and my wife have figured it out. Thanks!

July 25, 2012 Tg

The quality of this small amp is unbelievable. This completely resolved the low-volume output problem with my computer headphone jack. I am happy as can be! Thank you, thank you, thank you Boostaroo!

July 23, 2012 Kenny Rachal

Man just wanted to thank you guys! I've been having my little amp for about 5 years now with out any problems at all. Boosts my stereo volume loud enough to enjoy at hwy speeds 70 and above without distortion!

July 10, 2012 Ryan

I recently purchased a Boostaroo Revolution to go with a pair of Shure E4c headphones. The Boostaroo makes listening to mp3s on my iPod incredible. The Boostaroo really extends the headphones base response and all my music sounds crisp and clean. This is one of the few products that I've purchased in the past year that actually does everything it advertises. Makes long nights at the library much less stressful.

July 2, 2012 Howard Mayne

I found out about this site through a Delphi forum. I read the site and reviews. I didn't know if "doubling" the sound was going to be enough for my Sirius radio I installed on my motorcycle. I happened to see the Boostaroo at and took a chance, thinking if I didn't like it I could return it. I installed it in the parking lot and about blew my ear drums out! I had forgotten to turn the volume down on the radio.I am more than happy with the volume and quality of this product. I should also say my cruiser has modified pipes, a windshield and I use external headphones (not earbuds). I hear as much music as I want or as much traffic as I want. I highly recommend this product.

June 26, 2012 Mark

I love it. THE WORLDS BEST KEPT GADGET SECRET, WITHOUT A DOUBT. Every gadget or audio enthusiast should have one. I bought the basic unit, it to give me louder and clearer audio from my iPod. I often use it on my bicycle. I can fit the amp and my iPod all in my shirt pocket, and hear loud clear audio as I ride, without having to use ear plugs. The battery life is amazing! Mine seems to run for months. If you do not have one, don't hesitate. You really will not be disappointed.

June 21, 2012 Josh Broughton

I bought 2 of the original Boostaroo amps a while ago and fell instantly in love with them. I just got my first Revolution, and man what a joy of sonic bliss. Please give your R&D team a nice healthy bonus. I cannot wait to see what you guys (and gals) come up with next. I have made all my friends envious with your portable amps, while they spend twice as much and have to carry more weight to get the same sound quality that my Revolution gives me. The Rev, pushes my Sennheiser HD545 cans to highs I never would have thought. I'll end this and just say, Thank you for creating a awesome product, and as a owner of 3 of your products. I cannot wait till I can own the 4th, 5th,6th, etc products you produce. Keep up the great work.

June 20, 2012 Steven Lawrence

I'm SPOILED, and you have opened up a whole new world of ear candy for me. I already had an excellent (and expensive) pair of monitor headphones. I didn't think the sound going into them could be improved upon, but the Revolution did exactly that. Bolder, cleaner, more crisp throughout the entire range, with subtleties I never noticed before. I can no longer live without the Boostaroo. Absolutely incredible, so rich, and thank you.

June 18, 2012 Kurt Fraser

Just wanted to make a comment about the revolution. Was skeptical at first. I drive motorcycle long distances. With ear plugs, road noise, wind noise, engine noise, I just barely hear my satellite radio. Well I can't believe this little (big) device. I mean WOW!!!!! I had my satellite to the highest volume before the device. Then i plugged it in. At the lowest volume, I'm 100% louder. WHAT A DIFFERENCE. Its all I need, thanks, Kurt from CANADA.

June 11, 2012 Ashley Watts

I Love my Boostaroo Revolution! I can use it to save the battery on my iPod. I can play the volume much, much lower on the iPod - which means my battery lasts Longer between charges. And that's handy. Second, if I use it with my FM Transmitter in my car, I don't get The dreaded "static drift" because the added power helps it to lock On to my station as I'm driving. And, using it makes my music sound better than ever. Richer, fuller Like I'm right on stage with the band. So, that's a very good thing. And when I go home I can use it with my docking station or mini-computer speakers and get full stereo surrounds sound. Or, go to silent mode and just use it with my headphones. I get Home theater sound out of this little iPod and my Revolution. Thank You so Much Boostaroo!

June 1, 2012 Thomas

Recently uncovered a Boostaroo while digging for an HDTV audio system. Hooked it up between the headphone output of the TV and a Cambridge amplified speaker system. All I can say is WOW!!! The fidelity with the HDTV Surround Sound is AMAZING! Keep up the good work.

June 1, 2012 Rich L.

I recently ordered and received a USB Boostaroo, it works great and I was very happy with the service. Thank You

May 22, 2012 R. Crawford

My Boostaroo with my MP3 player is the only way to fly on my motorcycle.

May 21, 2012 Sonya

Ooo do I love this! Your Revolution makes my iPod sounds better than my home stereo. I wasn't that unhappy with the sound of my music, I just needed a way to overcome city noise. I bought the Bose Quiet Comfort headphones and thought that would help. They do, but still not enough volume. I tried the Revolution and I'm amazed. It's not just the volume increase. It changes everything. It makes it seem like I'm right up on the stage and getting down with the band.From now on I'm packing a Revolution.

May 2, 2012 SLawrence

I love my Boostaroo, not just for the amplification, but also the sound fidelity, which is amazing. It's not just an amplifier, it actually makes everything sound MUCH better.

May 2, 2012 Jeff

I've used my Boostaroo (Revolution I believe) for at least 5 or 6 years, perhaps more. I really only use it on airplane flights, but I fly a good bit and along with some excellent Westone earbuds that Boostaroo is gold! Plus I can share with my wife or my kids when they fly with me. Good product. Adds no interference - very clean - and does exactly what they claim, bumps up db nicely.

May 1, 2012 KennyR

I purchased the Bostaroo Revolution for Motorcycles as a pre-amp to boost the output from my iPhone and Ipod to my underpowered motorcycle amp and speakers. It worked as promised, and significantly improved the speaker output volume when riding at highway speeds with considerable wind noise.

I did experience significant audio line noise/distortion when first connected, but this was eliminated by use of an inexpensive 3.5mm audio line filter between the Boostaroo and main amp.

May 1, 2012 Andy Long

Got my first Boosteroo in 1999 to boost the signal of my portable Mini Disc player into quality headphones. It worked great, used for several years and loved it. Since my last divorce, I have not used headphones, yet the Boosteroo is a vital part of my home stereo system. I live on solar and wind power - trying to run most appliances of low power consumption. I use an original Boosteroo to split signals from various music sources into three Class-T 80w mono amps -driving a high end pair of loudspeakers and a 15" subwoofer. The sound is awesome and the Boosteroo adds no noise or distortion.

May 1, 2012 Andy

I just recently traveled out of the country and took my tablet with me to watch movies. I realized that even though the volume was at max, I couldn't hear it hardly at all. I stopped in Dallas to look for an electronics store and stumbled into Brookstone. I asked the worker if they had ever heard of an amplifier or headphones. They said no but have been asked several times the same question. I searched online on my iPhone and the first thing that came up was Boostaroo. It looked cool so I called customer service and asked if they had a store in the Dallas airport. They were sooooo nice and guided me directly to the store and I bought it. After trying it out I had to turn the volume down a little on my tablet. Great product!!! And even better customer service. THANKS BOOSTAROO!!!

May 1, 2012 Michael Mermel

There is no better way to hear music on a motorcycle than with an MP3 player coupled to a Boostaroo. The Boostaroo is capable of volume sufficient to overcome the wind noise, clarity is improved and the volume level doesn't have to "scream" to overcome the ambiant racket. It's the best!

April 27, 2012 Daniel A.

I hooked up the Boostaroo to a computer at my wife's office and then connected two sets of speakers so she could listen to Internet radio in two different rooms. Absolutely great sound. Thanks for the great product.

April 21, 2012 Robert Lehman

This is fantastic! I've had the original Boostaroo for years, as you couldn't quite hear DVD players in airplanes. It wasn't quite good enough to hear the speakers from my iTouch on my Harley, and so I ordered the Revolution. It is outstanding and works perfectly. Had to actually turn down the volume on the iTouch. Couldn't be more pleased. What an outstanding product.

April 20, 2012 Baydriver

This is an amazing unit that does just what it claims...amplifies any signal put into it. I recorded lots of voice mp3s and had a hard time hearing some of the files. The Boostaroo gave me just the right amount of boost to make every word intelligible. It works well in a car, plane, etc. I love it!

April 17, 2012 Mark Shearman

I Love your product. I was working a flight in first class the other day. The 2 people in 1A & B had no audio for some reason. I was able to hook up my Boostaroo to 2A and Everyone was able to listen to the movie. This made them very happy and I think you might get more sales. Thanks, Mark

April 13, 2012 Derek

I've had the Boostaroo for a couple of years now. It has been beat up, dropped, kicked and abused, but it still gives me excellent performance. I love this thing. It's the only way I can drown out the NYC subway, and enjoy musical bliss to and from work.

April 11, 2012 Ted Hoffman

Because of insufficient volume while watching movies on my laptop while in flight, I bought the Boostaroo. My wife and I used it for the first time over the weekend and it made all the difference in the world. We'll take no trip without it!

April 10, 2012 Carl Houghton

I bought this at a kiosk in the airport because my kids and I were tired of straining to hear our DVDs and other audio devices over the engine roar. This simple device makes a world of difference.

April 10, 2012 Harrie Gulikers

I needed an extra boost for my laptop so my twin-daughters can watch DVD movies while traveling. AND IT WORKS GREAT! Even low frequencies sound much better. Without the Boostaroo, the sound level was way too low, even with 1 headphone. Today I tried 3 headphones and they still outperform a single headphone without the amplifier! Thanks for keeping the promise! A very happy and relaxed dad ;-)

April 9, 2012 Bob Murray

I use the Boostaroo for the kids' TV. My 3 kids each have their own headphones with individual volume control. When we want quiet and the kids are watching cartoons, we just say, "Headphones!" and blessed silence descends. Also works great for the kids watching a DVD on the laptop on a go. Viva Boostaroo!

April 9, 2012 John R.

I recently bought this product and WOW! I wish I found it sooner! Half a year ago I bought a portable DVD player but I could never hear it in the car. Now, I can hear it with good clarity. If you have a product you can't hear well, buy this!!!

April 6, 2012 Billy

Works great. I have purchased four. Three for gifts and one for myself. Great price, arrives fast, and does what it promises to do.

April 4, 2012 Robert

Just a note to say thank you for a fantastic product. I am hearing impaired, and my television earphones were not able to provide sufficient volume. Your product was a lifesaver. I am now able to hear the television audio very clearly.

April 2, 2012 Beny Ben

Well, I have a pair of Sennheisers, and I just couldn't find a portable player who would give enough juice out to make the headphones usable on anything else than an home amplifier. After purchasing this thing, I was suddenly able to enjoy studio quality sound on the go to work.

March 29, 2012 Tim Martin

I have had my Boostaroo for a little over two years and it is unbelievable. I live in Chicago and take the CTA, subway/EL, everyday and the extra noise always cuts through a normal CD players volume. With the Boostaroo I never miss a note and those sitting close enough get to listen as well, I like it LOUD. It is also , usually, very durable as it has been bumped and banged around for most of it's life.

March 23, 2012 Ron Gilot

I received my Boostaroo yesterday. Very prompt service thanks. I tried it out with one headset and one set of earbuds. I can't believe the improvement and fullness of sound with the unit. I have been looking for something like this as I fly a lot and the drone of the engines doesn't always harmonize with my music. I think it will also be great hearing the sound on airline movies. Both me and my wife thank Boostaroo for your solution to our problem. A Boostaroo Booster Backer, Ron Gliot.

March 23, 2012 John Waller

Received this as a gift about a year and a half ago. What a treat, this is a tremendous value. Works great with mp3, walkman, cd player and laptop, allows multiple people to watch the same movie on a laptop!

March 21, 2012 David Sundell

I think you underrate the Boostaroo in you FAQ page when it comes to 32 ohm headphones. I've been using it with my Grado SR-60s, which are rated at 32 ohms, and there is a major improvement in both volume and sound quality. There are some great 32 ohm headphones out there from companies, such a my Grados and the Sennheiser 497s, which can be driven quite well by the Boostaroo and will give excellent sound quality from even a very underpowered MP3 player.

March 19, 2012 David De La Cruz

My TV doesn't have a headphone connector, it only has stereo RCA audio output. So, I was unable to connect my headphones to it. I learned about the Boostaroo in a electronics store. I bought it and it works very well. Now I'm very happy because, I can listen my TV without disturbing anybody else.

March 16, 2012 Janice Stewart

With me being deaf, I was unable to “hear” the sounds coming from my Sennheiser RS 180 seemed muffled and faint...but love the wireless headphone freedom as I can move about the house and outside to my patio. Today I received AC Powered Boostaroo Revolution Audio amplifier & WORKED! I can hear sounds comfortably...truly a magic.

I want to thank you all for helping me in every which way you could...and yes if any of my deaf friends want a set up like mine, I surely will refer them to you all.

Many, many thanks,


March 15, 2012 Henry Bennett

I purchased the Boostaroo recently and I think this is a must have for any portable music device. I have been using it as a line-out amp to my car stereo input and it works great. This little thing not only boosts your sound levels without loss of quality, but it also increases the battery life of your player. This is reading like a infomercial testimonial I know, but I am truly blown away with the versatility of this gadget. Thanks for a great product and Awesome technical support!

March 12, 2012 Robert Simpson

This great little tool allows my wife and me to watch and listen to a DVD on my laptop on long plane trips with ease. It is great!

March 8, 2012 Rob Boucher

Thanks for your help getting my Revolution repaired! I have three of them and have gotten some of my family on the also - great product!!

March 7, 2012 Gal Kremer

I had only line out in my laptop, which means the sound using earphones was very very low. I have bought a USB sound card and it was just a bit louder. I've recently got this amazing little thing called Boostaroo, and it works great! I recommend it to everyone.

March 7, 2012 Larry McCreary

Your product has proved VERY successful in my line of work (military pilot). Because I wear ear plugs while flying, I have been hooking a Boostaroo in series to achieve the desired volume.

March 6, 2012 Paul Tauger

I've just received my Boostaroo and couldn't be more pleased. I was considering buying a competitor's headphone amplifier that cost almost four times as much, but the Boostaroo does exactly what I need. I use it with noise-cancelling headphones when I fly. It puts out a clean, full-fidelity signal that lets me hear my music clearly. Great product, great price!

March 2, 2012 Rick Davitt

I use your amplifier with an MP3 player which is known for not great battery life and low headphone volume and this will help with both. Volume is better at lower settings.

March 1, 2012 J. Simmonds

With the Boostaroo the sound quality is outstanding even at 70 mph. Excellent product.

February 29, 2012 Ross Harries

I bought the Boostaroo after seeing it advertised on another website, when I was going to buy some speakers for my motorcycle helmet. I can only say how happy I am that I did! Without the Boostaroo, audio is virtually non-existant, but with it, I can now hear everything and can even turn down the volume! Excellent product at an excellent price - I have no hesitation at recommending this to anyone and am already doing so to my friends. Plus the service from the company was fantastic.

February 29, 2012 Angie Joyce

This will be the second Boostaroo I've owned--I used the first continuously at work. I'm afraid that the first one bit the dust, and I can't do without it! It adds so much to the sound that, without it, I'm lost! I've looked for another one for a while without any luck--I'm so glad I found your site!

February 27, 2012 Chase

Hey all I have just got my hands on one of these great devises. They help me hear my CD Player when I ride the bus. Also, when my friends want to listen to the CD I have they can just plug in!

February 24, 2012 Madeline Kripke

BIG-volume thanks to all of you at Boostaroo. My little unit came today (already!) and brightened my day. So far, it does everything it's advertised to do.

February 22, 2012 Les Cable

Tried your Boostaroo. It was last ditch effort at getting CD player heard over built in Honda Goldwing stereo system. It worked. Thank you for music on my wing.

February 22, 2012 Thomas Harding

After trying headphones to listen to MP3 files, I came to the conclusion it was just not loud enough. It was very hard to hear in a loud area, so I ordered a Boostaroo and WOW! Now it sounds GREAT! I love this thing. Great product.

February 21, 2012 Joseph Camara

I've had my Boostaroo for 5 years and I always bring it with me. bI love the idea of 3 of my friends to listen to music when they don't have a music player.(Giving is better than receiving.)

February 20, 2012 Todd Johnston

I do a lot of Motorcycle sport touring and I LOVE this thing!!! I'd been using a rigged auto audio booster to hear MP3 player and this takes its' place perfectly. I can hear my tunes thru my earplugs and over the road noise be it classic rock or German brass bands up to...well, very high speeds!

February 15, 2012 Rosi W.

I must say this is a really great thing for a medical transcriptionist.

January 23, 2012 Don Warn

The a/c powered boostaroo revolution audio amplifier & sound enhancer works fantastic! I replaced a wireless headphone setup with a wired headphone because the rechargeable batteries kept running down on a long weekend. But when my wired headphones were connected to the back of my DIRECTV box, even with my volume on my headphones turned completely up the sound was still very low. With this amplifier plugged onto the wire and my headphones plugged into it, the volume on my headphones is hardly turned on at all. This unit is so small yet powerful! Thanks, Boostaroo!

December 22, 2011 kevin

I got the revolution paired it with koss titanium pro 1a and it is so clear, even at high volume. I can hear every note. Crisp clear loud sound. Awesome product...I will be buying another revolution for my home.

November 29, 2011 Andy C.

Package received yesterday. Works very well.

November 13, 2011 Shuky

Believe it. I am using the first set of batteries for 90 hours of listening (about an hour a day during my walking time) and there is no sign of fatigue. Amazing. All that on top of the first class quality of the Revolution unit I have. I am very happy with this product.

October 30, 2011 P.K. Kaiser

I am very hard of hearing and originally bought the Boostaroo so that I could hear the audio on my iPad.

Recently I tried it with the headphone jacks on my computer because without it I could not hear the audio. With it I can.

Further I am impressed with how long the AAAA batteries last. I am still on the original batteries and have used it for several hours.

October 25, 2011 John R

Really pleased with the boostaroo. I use it on my motorcycle to increase the output of my satellite radio or Ipod which I can use with either blue tooth or via custom earplugs. A well built product with long battery life and just the right boost for my electronics products.

October 25, 2011 Autumn Hardy

I just wanted to say that I ordered your audio booster a few years ago with the same headphones that I ordered today. I do at-home medical transcription, and this device has been very helpful to me. I have hearing problems and after seeing an audiologist for a hearing test, he suggested I get an audio booster. I looked online and found your website. Just wanted to say how thankful I am. I even recommended you to some of my fellow transcriptionists!

October 22, 2011 Roy

Perfect for listening to satellite radio in Military Trucks!

October 21, 2011 mike

i love it, listening my mp3 in my motorcycle helmet with the Boostaroo is perfect.

October 21, 2011 Robert Comnell

I have several Boostaroo Revolution's. A must for the motorcycle Rock-n-Roller.

October 20, 2011 Lee Smith

We own two Boostaroo® Portable Amplifier and Headphone Bundles.We use one bundle to listen to the TV in our bed room. We love how clear the sound is and we replace the batteries very seldom.
we use the second pair of In-line Volume Control Headphones in the bed room so we can both listen to TV with one amplifier.
The second amplifier is used in my car to power a 4 inch speaker I use with my radio scanner.

October 20, 2011 Carol Weaver

I have two Boostaroo's and plan on buying a couple more. I have a severe hearing problem and my Boostaroo's allow me to enjoy television, music, the computer and most things that require hearing that my hearing aid alone does not let me do.
I wish that Boostaroo made devices that helped with the telephones as that is still difficult for me and the better phones for hearing problems are too expensive.
Thank you Boostaroo for making life a little better for me.

October 20, 2011 Brian S

I love my Boostaroo. I have a motorcycle helmet intercom system. One of the features is the ability to attach an mp3 player. The volume was never loud enough to hear well. Then came Boostaroo. Not I can hear it loud and clear!! Thanks Boostaroo!!

October 20, 2011 David

This little gadget goes to show that even though it's a little fellow it packs a giant size punch. I use it in the garden and car and I'm forever being asked what is that, I reply that's my Boostaroo mate !!.

A neat bit of kit, well done.

October 19, 2011 Michael B Miracle

I ordered the Boostaroo to help improve my volume coming from my computer to my home stereo. I was pleasantly surprised that it added the volume I was looking for. It was very easy to hook-up and all I had to do was adjust my computer volume such that it didn't distort. Don't know how many decibels it increased but all I know is the music coming out of it now is much improved. The only thing I regret is that I didn't know about this sooner. Very satisfied with purchase.

October 19, 2011 sandro

It really does improve the sound quality and boost the volume too! Those AAAA batteries can be more difficult to find in some stores though. I would rather have triple A batteries, they are more common even though they are a little thicker.

October 19, 2011 bill

Have 3 all of them fine. Use the smallest one on my Honda Goldwing Motorcycle to boost XM radio signal and iPod signals back through the speaker system.
Challenges on AAAA models 1. batteries are hard to find. 2. without a switch and light to remind me to shut it off I have left it plugged in and drained the batteries in a few days. Make more stuff...

October 19, 2011 AdamR

Hello, I am probably one of your first customers! I still have the Boostaroo. I purchased it for riding my motorcycle and it has never failed. I probably have over 70k miles with it.

Thanks again for a great product I could not do without.

-Adam R

October 19, 2011 Bryan Ong

I live in Malaysia, in South-east Asian region. During my leisure time, I like to hook up my laptop to LCD TV to watch various media contents. I use Boostaroo (the model that uses two AA-size batteries) to boost my laptop audio output to my home theatre system (with Y-cable). My encounter with Boostaroo has been a pleasant one ! However, there is always room for improvement for Boostaroo.

Technical aspects
I would prefer a model that can be powered with either batteries (AA or AAA, the common sizes) or USB port. I really look forward for this versatility. Personally, I think Boostaroo is of great use for computer users, especially laptop users. I never use it with my earphone, loud sound is bad for ears. Secondly, I would prefer the plastic housing to come with solid color, instead of semi-transparent one. It looks ugly to see the circuit board, the batteries and the sponge around the batteries.

Marketing aspects
Like I said previously, Boostaroo is great for computer users. Perhaps, the company may consider a tie-up with computer manufacturer like Dell to bundle Boostaroo as accessory. I think many would be happy to have it by looking upon laptop and LCD tv are getting more affordable these days. In fact, many though not all, prefer to play their video and audio contents straight from their computer instead of going through conventional dvd/vcd player. PC provides great flexibility over conventional entertainment appliances.

Ok, that's all for my feedback. Adios !

October 19, 2011 Mr. Jay

I am a musician/DJ also working in the radio business. Discovered that the audio output from my headphone jack on my laptop didn't have enough punch to feed the station mixing board, levels to low. Searching the web, found the Boostaroo. What a perfect product. Simple in design, small and compact and gives me the exact boost I need for radio work or for feeding into my DJ gear. I'm also an Electrical Engineer and can really appreciate the engineering that went into the Boostaroo. Fantastic product guys (and gals). MRJay

October 19, 2011 Howard

Installs like nothing easier, works fantastic!

October 19, 2011 Mark Nelson

They start working well, but it doesn't last long. The jack input is the culprit. I have two of them, and now they work nicely as doorstops. Shoddy materials and poor workmanship makes these a poor choice. I contacted you people, but was told there was nothing to be done. Now, I will do nothing and avoid these like the plague.

October 19, 2011 Tony York

Great product, especially when sharing a media device and sound levels drop and things like aircraft noise takes over. Boostaroo fixes that no problems. Only downside is use of AAAA batteries, which are not always readily available, so make sure you buy a spare when you by any replacements.

October 19, 2011 Vicki

Yes indeed I love my Boostaroo. After getting a netbook and wanting to watch a DVD on the player in the car or listen on a train forget it with the regular volume on a net book. Terribly low. I talked to my nephew who has a computer business and he recommended the Boostaroo. Saved my listening times in the car or train or plane. Wonderful wonderful. Thanks to the audio amplifiers at Boostaroo.

October 19, 2011 Amps

I have a 2011 Harley Limited with a Garmin 665 Navigation and Xm radio built in the garmin...The 8mm jack from the Garmin goes into the Boostaroo and then into the Aux. Jack of the radio.The Boostaroo is hidden in behind the radio..Wow the increase in volume is fantastic. Worth every penny..

October 15, 2011 Kimberly Barros

I found the Boostaroo perfect for my Panasonic flash video camera which had a microphone out but not a headphone out. A complaint on Prosumer Videocams is that they lack a headphone out, but this unit solves that problem. Using the Boostaro with a y stereo female adapter connected to the a/v cables, I was now able to monitor the signal and adjust the auto gain control (AGC), and volume coming in through the microphone. The headphones can also be switched out to a more sound proof type unit to eliminate external sounds for monitoring in a noisier environment. Great value product and highly useful.

I recently purchased a Boostaroo portable headphone amplifier and splitter from Radio Shack to help boost the volume of my mp3 player on my autocom system during a recent 5000 mile trip to Canada on my motorcycle. The unit performed fantastic, and I was amazed at how long the batteries last.

I use my boostaroo revolution to amplify the music from my mp3 player to my monster clarity speaker. Before using the Boostaroo some songs I downloaded had low volume now they come in loud and clear. Great product I love what it does for my music. I'm a portable girl because of my job. Scheduled Bus driver.

Wow! I bought the Boostaroo with the inline volume controls to solve a low output problem with a new Toshiba Thrive. I'm using Sony MDR-22NC ear buds, and even at a low impedance of 15 ohms there was nowhere near enough volume unless you're in a library. I plugged in the Boostaroo and problem way more than solved. I bought the two inline volume controls so my wife and I can enjoy movies in flight at our own comfortable listening level. This is an excellent product at an excellent price. There's enough gain in the Boostaroo that I could turn down the output on the Thrive and still get plenty of volume. I never heard of this product, but having bought and used it I, as a retired broadcast engineer, highly recommend it.

I have just received today my Boostaroo rev. amp. I use it on my sport activity and I am very very impressed and satisfied from the great sound. I am still concerned about the availability of AAAA batteries in Israel at this moment. Bottom line - very happy.

I am hard of hearing and have two Boostaroo's at present and plan on buying more. It really is a great product. I use it for TV, DVD, Laptop and iPod.

Your Boostaroo T613 volume booster was a godsend for me so I can hear better on DVD movies and learning computer skills.

Thanks and keep up improving your products...

I ordered one to listen to satellite radio on my motorcycle, but once I received it I realized that it did not have a built in volume control to regulate the volume going to my helmet so I had to order that as well (the schematic diagram on this website does not show a volume control). It worked good for about 2 weeks, then one of the connections inside came loose. Rather than re-order a new one, we soldered it back in place. Then the output plug came loose (hey, motorcycles vibrate) and we put epoxy on it. First trip this year it stopped working and we don't know what is wrong but we can hear something rattling inside. Just beware that these are very fragile units. I think I will be looking for something a bit more durable.

--- Follow Up From ---

Our amplifier units do not come with a built-in volume control. In most cases, the user is able to adjust the volume directly from the audio source. We do offer volume control cables that can be purchased as accessories to all of our amplifiers.

With our R234 amplifier models, the LED cap has an extension built in to funnel the red light. This can sometimes rattle inside the unit.

The customer made no contact with us to deal with the broken amplifier unit. We offer a 90-day return policy and a full 1 year warranty on our amplifiers. We could have easily shipped them a replacement for their unit. We take pride if offering reliable amplifiers. If there is a problem, we will help remedy it.

The Boostaroo Revolution was an easy way to boost the signal from my iPod to my amplified motorcycle speakers and get even more sound from them allowing me to enjoy my music on my road king (loud pipes) even at highway speeds.The only drawback is that the unit is not weatherproof and even though I installed in as dry a location as I could, it crapped out after two years of use. Still the best option out there and I'm ordering another.

May 31, 2011 Kenneth Bradley

I used the Boostaroo t613 on a flight from Dallas TX to Dubiax I used less than 20% of my iPod battery. Used sure 3 amp ear buds and never missed a sound.

May 15, 2011 Bill Alberts

Had a Garmin Zumo 550 installed on my motorcycle. The unit is wired so the sound comes through both the external and helmet speakers. The volume was terrible and after some research discovered this is a known problem with the Zumo 550. I purchased the 12 V Boostaroo Revolution and the volume is excellent. I actually had to turn it down one notch.

May 12, 2011 Diane Furber

This item is fabulous with our wired headphones with inline control by Sony. This product solved the problem with upgrading to a LED HDTV that had no headphone jack and one a LCD HDTV that had a headphone jack. With the dual split that we use with our headphones the sound was cut in half on both TV's and NO ONE knew how to work around it with the headphone we use and like. Radio Shack suggested the battery Boostaroo and it worked fine but we prefer not using batteries. A search on the web and we found your company. I have read so many ratings on HDTV and people having exact problem we were having and did not know how to work around it. Plus we bought our two TV's to upgrade into the 21st Century and neither vendor could give us suggestions how to remedy the amplifications of our headphones. We sing your praises!

May 11, 2011 Mark McMarkio

I do not understand the technology involved, but, boy, can I hear a difference on my Bose headphones.

April 27, 2011 Rick Bertolette

Hello, just a short note-just purchased your Boosteroo model T613 at my local radio shack and am impressed at the quality of sound I am getting and the saving of battery power I save on my BlackBerry Torch smartphone. These phones use a lot of power already, your product should be sold where BlackBerry and other high end smart phones are sold. The sales person at Radio Shack told me and sold me on your product, but seeing it hanging on a peg on a wall really didn't do your product the justice and respect it rightly deserves.Your product needs a display that people can try and be amazed by. Well thank you for your time and a great product, take care and have a great week. Respectfully, Rick Bertolette Lemoore, CA

I do sound for a southern gospel group. We were using a self-powered mixer, with a 1/4" SPEAKER LEVEL output, but no HEADPHONE output, so, from the mix position at the back of the room I couldn't hear the on-stage monitors, to do a mix for the musicians. I had a LINE LEVEL output on the mixer from the monitor bus, that I was able to plug the headphone amp into, (using 1/4" adapter) and subsequently, was able to hear the monitor mix in my headphones to set-up the proper mix for the musicians onstage. Great sound!

December 29, 2010 Joshua Shuky Naamani

I bought T613 and it made me very happy. The result of this item is outstanding. However' some points for the product designer:1- There must be a hole to attach a lanyard to hang on the neck or put on belt. I use it with my Sansa Clip for sport.2- The red "on/off" light is not well located. Can not be seen easily.3- Inserting the bateries is not as easy as should be.

December 22, 2010 Mike

Wish I knew about this when I first got my iPod. It's a must have if you're using big headphones. The 250 Ohm Koss Pro 4AA I use seemed ok with the iPod. Then I figured out what I was missing in detail and dynamic sound with the Boostaroo Revolution now the iPod isn't struggling to drive them. It's made in the USA too!!! Good Job!

December 15, 2010 Vic

That booster works great. It made a big change in the sound. Thank you

December 6, 2010 Chris Kanaris

Great piece of kit. I'm and electronics engineer and was about to build one of these

November 16, 2010 John Weaver

Your R-234 model got here and works great for boosting the helmet speakersso NOW I can hear my MP3 player while riding my motorcycle.

November 9, 2010 Rusty Smith

A very versatile device that I use to increase volume of my MP3 player for input into my home stereo aux input

November 9, 2010 Michael Berkowitz

Very Impressive! The first thing I did was hook it up to my iPod Classic with Bose headphones. The sound quality and frequency response was outstanding. Thank you for making such a great product

September 8, 2010 Luis D. Amaro

WoW...WoW!!!!!! Wooooooooooo!!!!!! I Love this $%!#. Hardcore amplifier and you can't get any better than Boostaroo

August 23, 2010 Kenneth D.

I use your product to enhance the sound quality and volume for my MP3 player while I ride my motorcycle. Works great!

August 17, 2010 Patricia Lucas

I am a legal transcriptionist so hearing every single word or utterance is critical to my work. I had a piece of audio that was very faint and I just could not hear it no matter what volume boosting software I ran it through.I had heard of Boostaroo from colleagues at a transcription forum I am a member of (Transcription Essentials) and decided to try it. WOW! It boosted the audio so much I actually had to turn the volume down! It was so easy to use

August 4, 2010 Christine M.

I have recommended Boostaroo to all my Scopist Support Group members. Your product works well

July 12, 2010 Chuck C.

Hi..I had one that was handy as heck. Lost it last weekend in Cody

boostaroo this item is kicking. Good power

June 8, 2010 tim

the boostaro product is the best. i use it for my car by plugging in my mp3 player and playing through a radio transmitter. it works great. i would recommend this product to anyone and i have recommended it.

June 1, 2010 Joe Stiehl

I hook my Boostaroo to my laptop then to my external speakers. The sound is "boosarooed" using less volume and no distortion. I use it for music as well as movies. The quality of sound is fantastic and now fills the room and I can take it anywhere in my laptop case. Simply the best!

May 25, 2010 Gloria Thompson

We truly LOVE the Boostaroo amplifiers we got to go with our Sony headsets which we use only for air travel. Prior to your product

May 25, 2010 Debby Thomas

I do enjoy my Boostaroo tremendously and it works great on recordings that are difficult to hear!! Thanks for a great product!

May 24, 2010 Carole Taylor

I LOVE my Boostaroo!! I hook my Ipod to it in my car and WHAT A DIFFERENCE!! Better quality sound thru my speakers and only have to recharge Ipod every 2-3 weeks!!! You GOTTA GET ONE or 2 or 3..............

May 21, 2010 John Dieudonne

My order arrived and is EXACTLY what I needed for the application. Wish I had known about this earlier.Thank you.

April 30, 2010 Brion Pollock

Works great

April 19, 2010 Norma

Received the headphone bundle package this morning and am quite impressed with it. It will be used primarily in the car to listen to music on my GPS. My wife can listen in at a different volume to me. Thanks for quick service.

March 29, 2010 Mark Mayes

Great product. Works well to boost satellite radio output on way to the car stereo input jack.

March 25, 2010 Peter Wing

It works GREAT! You have a fine product.

March 23, 2010 Randy Zitch

Very pleased with unit. It works better then expected.

February 26, 2010 Cindy Richardson

Very happy with my amplifier. Just wanted to let you know.

February 26, 2010 Brad Gilbert

GREAT CUSTOMER SERVICE. I recently purchased a Boostaroo Original for usewith my CREATIVE ZEN MP3 player and TORK XPRO helmet speakers. I found theOriginal just didn't provide the volume increase I was expecting. Icontacted the customer service department and explained my situation.Their support guy advised me that it was underpowered for my MP3 player/speakerselection and the Boostaroo Revolution was the appropriate unit for myuse. I was immediately offered the option of a refund for my purchase or anexchange for the Revolution. Really refreshing to find excellent customerservice like this!

February 22, 2010 Steve Schindehette

I purchased the 12V Boostaroo in order to install Sirius radio on my Yamaha FJR1300. I purchased a totally cool "Fuze Block" and wired the Boostaroo into the block. AWESOME!! Now I can actually listen to the radio with clarity and volume.

February 12, 2010 Marcia

I'm a medical transcriptionist who is losing her hearing because of long-term prednisone therapy. One of my bosses had me order a little Boostaroo amplifier for my PC headphones quite a while ago

January 14, 2010 Jim Bednarz

Dear Boosteroo:I have had my Boosteroo for a year and have had NO problems. I attach one end to my little ZEN V Plus and the output to my Bose QC-2 headphones. Result? My volume on the ZEN is at 6 when I used to have to blast it at 14 or max it out to use it when walking. It is that good. Well done! I always demo the product by taking it off the boosteroo and then hooking the boosteroo back up. Everyone notices the difference. Great product.

January 13, 2010 Helen H.

I am profoundly deaf and for a long time just used my Boostaroo with an iTouch. Last night I tried it with my Apple laptop and for the very first time in the five years I have owned it I could hear the audio.

I'm VERY disappointed in the product that I purchased

November 12, 2009 Ray W.

I have used 2 Boostaroo products on many long flights with Bose Quiet Comfort 2 headphones. Works perfectly. Thanks for a great product.

November 10, 2009 Joan Kohler

Thank goodness for Boostaroo! My dad had trouble distinguishing conversations on television and had virtually stopped watching tv. The amplification of Boostaroo has now allowed him to hear all tv programming at a lower volume and much greater clarity. This is a great product

November 9, 2009 Alex Y.

Your Boostaroo for Ipod with up too 400% increase is the best toy I have had all year...It even beats the Rolex for my birthday!!!It gives back the volume I use to get out of my first Ipod 8 years ago..but does not give enough to distort the music.I finally after 4 years

November 4, 2009 BILL LANE

I purchased you 12 volt amp for my 2010 Harley Softtail Deluxe.I was looking for a small consealable amp to boost the output of my Sirius plug and play receiver. What a product. I can listen with ear plugs with your inline volume control at less then half volume.The biggest asset to your amp is it already has 3.5 in and 3.5 out

November 2, 2009 Rocky

I am using the Sony MDR-EX85 earbuds with the T613 battery amp. They are supposedly rated at 16 ohm with 5khz- 23k hz rating. I have it to my PSP and it sounds awesome.

October 20, 2009 Mike K.

I like your product so much!!! It's awesome! On the internet there are amps which cost 100's of $$$ But Your product is just as good as them!!! High Tec!

October 6, 2009 Michael K.

Many Thanks to you and the inventor.You did a wonderful job with packing and shipping it

September 30, 2009 Carl Englund

Finally got my boostaroo today! Not that I have been waiting very long. Great product.

September 28, 2009 Michael

I just received my Boostaroo Revolution today and tried it out. It's fantastic! I have a pair of very high end pair of headphones.

September 7, 2009 Galen E. Clothier

I have a severe hearing loss and wear bluetooth enabled hearing aids. I purchased a Voiis stereo music bluetooth adapter for TV audio but the signal was not loud enough. I then purchased your AC Powered Boostaroo Revolution and now the signal is perfect along with very high quality audio. You need alert others with bluetooth adapted hearing aids (with a streamer) about your product. Thank you for this excellent solution to my problem.

August 15, 2009 Gloria

We are seniors who travel by air a couple times a year. Our DVD player was impossible to hear (despite the fact that we were using Sony Noise-Cancelling headphones). Alas....our salvation was the Boostaroo Revolution Hi-Fi Amp.

August 14, 2009 Wesley Doyle

I have Boostaroo for my computer and its wonderful.

August 11, 2009 Marshall Baker

I received your AC Boostaroo and am so satisfied! The sound volume -- as I thought it might -- is a major improvement over your battery model.

August 6, 2009 Ricky Polnor

Thank you for the incredibly fast delivery of my order.I orded it from France on Aug 3th and get it in my mailbox on Aug 6 !!!Boostaroo works perfectly! Exactly want I needed and expectedGood Work !

July 29, 2009 Bernhard Pukl

Thank you for the incredibly fast delivery of my order. The Boostaroo is a great device to boost the volume of my iPod!

July 28, 2009 Gray Walker

JUST AS ADVERTISED!! Got confirmation it was in the mail within hours of order. Arrived Priority Mail in just 2 days.Boostaroo works perfectly! Exactly want I needed and expected. Using for a boost when using earphones on TV at night. Will be ordering another for 2nd TV. Money well spent.

July 23, 2009 William Burrows

Just got my Boostaroo and it works great.

June 15, 2009 Arthur A. Hayner

I just bought your original (3 splitter) Boostaroo from RadioShack and LOVE it! I expected little boost and lots of distortion but instead got the boost I needed and no distortion even with my MP3 player turned all the way up! I'm using the Boostaroo in my car with my Archos 605 MP3 player which I play thru the car (Ford Freestyle) stereo. My problem was that even with the Archos and the car stereo turned all the way up some MP3's just didn't play loud enough to hear when the car windows were open. Now my problem is solved! Thanks for the pleasant surprise of a great product that exceeded my expectations!

June 14, 2009 casey

Installed an XMP3 portable sat system into a new Ford Mustang. Also installed gateway network bus to enable the system to operate with the OEM stereo. The Boostaroo saved the day. line out power from mobil radio very poor and system install is useless without the Boostaroo. easy to mount and the power supply being a cig lighter is perfect. I will be buying a second unit.

June 11, 2009 Prokopis Totkas

Input signal from my mp3 player to the aux in of my car radio cassette CD player was very week.Then I bought revolution Boostaroo and the problem was solved at once.Now I hear louder sound with the best quality and most important without spending money to batteries.Thank you very much people.

May 22, 2009 darrus

I just love my Boosteroo! Only problem is... I have to hide it from the kids!

April 17, 2009 Richard Gerber

LOVE your product on my long motorcycle rides. Many repeat purchases and have passed on tips to many others to buy your good stuff!

April 16, 2009 Tom Caloia

Just wanted to thank you for a great product. My 95 year old Dad needed just that little extra "Boostaroo" in order to listen to the TV at a volume that's comfortable for himself.

April 16, 2009 Ira Rosnel

The Boostaroo Revolution is a great product. I just purchased my second one.

April 7, 2009 Mike Ward

How many times can you say "THANK YOU" to such a great company with super people with such outstanding products?

January 29, 2009 Charles Perry

I ride a Harley Davidson motorcycle with a factory stereo and upgraded speakers. My stereo has sufficient volume, however; when I input music through my Ipod, I lose approximately 25% of my volume. I received a Garmin Zumo 450 for Christmas and it has a built in MP3 player. When playing music through the Garmin, I would lose approximately 50% of the volume. I considered purchasing an amplifier at a cost of around $400 until I learned about the Boostaroo. I figured I had nothing to lose because if it didn't work, I could give it to my daughter. I went riding this past weekend and I am very pleased with the Boostaroo. It brought the volume from the Garmin MP3 player to a level just slightly above the factory stereo. Instead of keeping the volume at 100%, I now keep it at 50%. I would not be able to use my MP3 player without this product. The only drawback is that it operates on batteries. Since this will be a permanent part of my motorcycle stereo system, I need a product that can be wired into my electrical system (inside my faring). I have been informed that one will be available in the future and I am looking to purchasing one when available. I highly recommend this product.

January 13, 2009 Leo Dewey

I just had to write to let you know I received my order today and to thank you for such an outstanding little miracle device. I had been put off for awhile by unfavorable user reviews on Amazon, but as I read more of them I began to suspect that some were by people who had no notion of the relationships embodied in Ohm's law.

Your tables of specifications clearly showed that the battery-powered and AC/USB models were identical, except for their power source, and that Boosteroo's effectiveness related directly to the rated impedance of the headset connected to them. However, some people just don't get it. I do, and am very happy with your product: the best little amplifier I've ever tried - hands down.

My endorsement is based on several decades of listening through various audio devices since I have lived with a hearing impairment since age 12 (now 62). So I have had many disappointments along the way. Not with Boostaroo, however. As soon as I received your package, I ran a non-scientific test, finding the weakest audio signal station on our new HDTV and, with my 24-ohm Sony Studio Monitor headphones connected directly, adjusted the TV volume to the level at which I no longer had to lip read to understand what was being said. That level was 90%. I then connected the headset to my new Boostaroo and increased volume from zero to the same hearing acuity level. That reading was 25%! In fact, I couldn't go beyond about 40% without risking damage to my ears or the headset.

In my book, that signal boost is better than outstanding, especially since I could detect no distortion or noise at any frequency. Amazing! I no longer have to drive others out of the room turning up the volume on our external sound system so that I can hear. I can now just use the separate, pre-wired headset directly from the mini-plug circuit on the TV for my level of stereo audio. I can't thank you enough, and my family thanks you too :-)

I finally received my order and I just wanted to thank you for it. The 'Boostaroo Revolution' works just wonderful... it's does everything you claimed it would do.

Due to my advanced age I have to use earphones to enjoy my music and most of all my television programs. This small piece of equipment works miracles and since usually TV Channels deliver audio at different values the volume control is a big plus.

My other hobby is 'Flight Simulation' and my problem it's still the same. Hearing deficiency. So I may consider purchasing one more set.

Thanks again and good luck !

January 1, 2009 Joe

Anyone who has driven any late Rover product with an aux. input should buy this product. The Rover aux. 3.5mm connection offers very poor sound quality at very low levels. Here is a product that more than compensates for both problems. The Boostaroo makes the otherwise very poor aux. connection in a Rover sound like a CD- The best $30 you can spend on a Rover!
