I hope you enjoy this 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!  

I was pleasantly surprised, by the increase in sound! My Sansa 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!  

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!!  

Jaw Breaker, if you ever listen to your music with this you will never be able to go back....brings new life to audio product...small and powerfull......  

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.  

I've had my Revolution for about two years now and love it on my long motorcycle trips! Recently lost the battery cover, called them and was sent two covers, no charge! Gotta love that service!!  

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!  

Just a note to say we love the amplifier earphones! (and 1/6 the price of TVEARS) The whole purchase experience was great! We will do business again.
Thank you, Lee Smith  

I discovered Boostaroo at a local electronic outlet 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.  

I'm looking for an amp like the boosteroo that will BOOST THE HIGH FREQUENCIES much more than lower. I have high freq hearing loss and have earphones connected to TVs. Thanks.  

Just a quick note...I tried this yesterday with my .mp3 player and my slightly loud piped motorcycle...excellent results. Music on the road...I love it.

Thanks for a great deal!!  

Just received my Revolution today. Delivered in 7 days to Germany.
It's absolutely what I was looking for - anyone who is frustrated by the sound caps on new European bought ipods should get one!
Great customer service, too!
Will be recommending to anyone who will listen!  

I bought the Boosteroo at Best Buy 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 Verizon 9400 tv cell phone.It is fantastic and sounds incredible.  

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 hi-def model. Thanks for a great product.  

Just an update to my earlier testimonial below. UpBeat Audio came through for me and are sending me a replacement cover for my Boostaroo Revolution!

Customer service to the rescue!

P.S. The first two of six AAAA cells I pulled out of my Energizer 9-volt battery are still going strong!

Michael H.  

Bought a Boostaroo Revolution about a month ago for my PSP. The PSP's untouched audio is very muddy and there's absolutely no separation in sounds, etc. With the Revolution attached, it's like night and day. Downright awesome actually.

Only gripe is the cover tends to pop off quite easily. I lost mine and innocently inquired about a replacement (e-mail ignored), but other than that, the product works fantasically.

The use of quad-A batteries was actually a brilliant strategy. Just last night, mine ran out for the first time and I went ahead and bought an Energizer 9volt battery, pried the battery's case open with pliers and plucked out the six cells inside. They're a tad short for the Boostaroo, but they work. Pop the negative terminal of the 9-volt off and use it as a bridge between the batteries and the amp's terminal.  

WOW! The amp arrived this evening. It is AMAZING.  

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

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 mp3 is so much cooler now.  

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

Sincerely JT  

I ride motorcycles. Listening to road tunes through an MP3 with headphones, I've always fought both road noise and volume problems. The MP3's just can't pump out enough volume to overcome the noise. Skeptical as always, I nevertheless bought a Boosteroo for $29.95, absolutely convinced I'd return it. WOW! Was I wrong. It's better than I thought. The sound quality is fantastic, and the volume amazing. Even at 85 on the highway, I need to turn the volume down on my MP3. I couldn't be more pleased. Cruised around all day today with crisp, clear, LOUD music. Thanks.  

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 using my iriver clix. 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.  

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. I now have the computer volume on 1/4 and the speaker is gone! THANK YOU FOR A PRODUCT THAT WORKS.  

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 first gen 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.  

Wow you guys are fantastic kudos for customer service.
oh yeah the amp is making my ipod sound soooooooooooo much better even without the door.

Thank you

Happy Boostaroo freak Will Cage  

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.

Thanks.

Bill Bryant  

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,

Mark Steffens  

This little gadget really works. I had tried my Dell Axim (has
windows media), simply saving cd's to CF cards- they play, but sound is
just too weak. The Revolution is the missing link- I've tried it with my
Cowon MP3 player, my Axim- where it really shines is with any of the
portable/battery powered speakers. It really boosts the JBL on tour,
Virgin Boomtube. Best of all is with my Teac R100 rechargeable radio
(like tivoli pal) - the MP3, PDA really perform when plugged into Aux. You
should contact DEll- the Revolution transform the Axim into a genuine
multimedia device.
Michael Holmes  

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!  

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.
Boost my stereo cassette player volume loud enough to enjoy at hwy speeds 70 and above without distortion!
Thanks again!
sincerely,

Kenny  

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.  

I found out about this site through a motorcycle forum on Delphi forums. I read the site and reviews. I didn't know if "doubling" the sound was going to be enough for my Sirius sportster radio I installed on my motorcycle. I happened to see the Boostaroo at Best Buy and took a chance, thinking if I didn't like it I could return it easier. I installed it in the parking lot and about blew my ear drums out! I had forgotten to turn the volume down on the sportster 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.  

Hi I ordered Your Revolution Amp. IT'S GREAT! I use it with an old Sony Walkman with a tape player . I record tapes and it even makes them sound awesome. I hear stuff I didn't know was there . I'm 39 and a janitor at a nursing home and I use it daily at work and play. I've been using a walkman for years. It really makes my Neil Young songs sound even better. Great product! I use Bose headphones. Really sounds good , Mark  

Hi.
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 at the gym from PDA for audiobooks and from ipod. It does this perfectly. Other uses are at the football to share the radio with my kids.
I often use it on my bicylce with a cheap tiny Crest SF-10 stereo speaker.
I can fit the amp, speaker and my 80 gig ipod all in my shirt pocket, and hear loud clear audio as I ride, without having to use ear plugs (which I think are dangerous on a bike).
The battery life is amazing ! Mine seems to run for months on AA's....even if I don't turn it off.
If you do not have one, don't hesitate. You really will not be disappointed.
 

just received it a few days ago and am REALLY happy--i attached it to my 5G i-pod's leather case using 3M double-sided tape-it looks good and sounds AWESOME--i am a musician and am used to loud volume--this works-not only loud but great definition and quality sound--it pumps up my work-outs like crazy !!--only niggle was i only recived one cable --the longewr one -instead of 2 like i have been seeing in reviews and websites--maybe that changed--anyway this does nothing in detracting from the volume and sound---thanx for making such a quality and fantastic sounding product---Joe L.  

Love your stuff. Any plans for a USB powered Revolution? Currently drive my (2) PC/(2) entertainment center criss-crossing setup with a trio of boostaroo products. 4A batteries are a bit of a pain to find and keep me from picking up a second Revo.  

I bought 2 of the original Boostaroo amps a while ago and fell instantantly 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 Reference cans to highs I never would have thought, that my Rio Karma and CL Zen Micro could have sounded so much better with these portable amps.

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, ect products you produce.
Keep up the great work. I cannot wait to see what you come up with next.

-Josh Broughton (Loyal Boostaroo customer)

thank you all.  

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.  

I ordered your amplifier and it worked great. We had a 32 year old cassette of my son that was difficult to hear. When you max the record volume the "noise" was terrible. I don't know why but through the amplifier it turned out great. Thanks  

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 satelite radio. Well I can't believe this little (big) device. I mean WOW!!!!! I had my satelite 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.  

My personal comment; I always look for the specs, and I was truly amazed at what the labs are saying..
It's been my experience that some line noise is added in any connection, and losses are incurred. This device is incredable, I have an inexpensive, new generation,mp3,wma,CD disc player and my playback copy and playback is at 192mbps. Your basic unit with three outputs is perfect with my phonetopia selection and those specs are from 6-3200mghz your uint does the entire spectrum, as far as I can hear, without adding anything but pure, sweet punch!!!  

I pimped my stock car stereo out using 2 of your Original Boostaroos and a Boostaroo Revolution. The sound is amazing, it's like having a $500-$1000 dollar car system installed, and I only spent $119.97 on the whole thing. Not only that, but I wired the units directly into my stereo allowing me to have an auxillary in port for my iPod. I have never heard my music sound so good. You should see the looks that I get when I show people the inside of my trunk after they hear it. (There's nothing in the back but 2 6x9's) =)

You guys rock!!!  

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. Plus, replacing An iPod battery is mucho expensive, (like, over $100 and it means I have to send it in to do that, so I'm iPodless for a couple of weeks. Who needs that? So, anything I can do to put off that dreaded day is a good thing.

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. Another good thing.

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 theatre sound out of this little iPod and my Revolution. A very good thing.

Thank You so Much Boostaroo.com!

Ashley  

Recently uncovered an "original" Boostaroo (grey case) while digging for an HDTV audio system. Hooked it up between the headphone output of the TV and a Cambridge SoundWorks amplifed speaker system. All I can say is WOW!!! The fidelity with the HDTV Surround Sound is AMAZING! Keep up the good works... Ashley Watts  

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

My Boostaroo with my mp3 player, it's the only way to fly on my motorcycle.  

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 headsphones 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 gettin down with the band.

From now on I'm packin a Revolution.  

There is no better way to hear music on a motorcycle than with an MP3 player coupled to a Boostaroo, heard through a set of noise cancelling headphones. (Sorry Goldwing and Ultra Glide riders, but you know you can't really hear the music well through speakers with 60 MPH wind going by). My set-up is a 1 gig flash memory Sandisk MP3 coupled with a velcro strap around it and the Boostaroo to make the pair a handy pocket sized unit and tame the "cord clutter" heard through a pair of cheap, ($20.00) noise cancelling headphones I picked up at a PEP BOYS auto parts store. The noise cancelling phones are a must, because although the Boostaroo is capable of volumes sufficient to overcome the wind noise, with the noise cancelling phones, the clarity is improved and volume level doesn't have to "scream" to overcome the ambiant racket. It's the best  

I hooked up the Boosteroo 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. Works great--except only one speaker works in each room. I then solved the problem of only one speaker working in each room.

A quick Google of this issue suggested that if the plugs aren't all the way seated into the sockets in any set up, you get only one speaker. I pressed them in harder and voila! Absolutely great sound. Thanks for the great product.

 

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's a little large for carrying around with an mp3 player, but works well in a car, plane, etc. I live it!  

I Love your product. I recommend the 3 ft. cord though for a few extra bucks. 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  

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.  

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!
Thanks,
Ted Hoffman  

I just recently received my Boostaroo in the mail. I have to say, I am more than pleased. One of the reasons I bought the expensive PDA I did was because it has an embedded mp3 player...I was sad to discover its weak audio output capability. Thanks to my Boostaroo, I'm getting my full money's worth and my friends can listen along with me in Stereo!  

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.  

QUOTE:"My Boostaroo was shipped on Jan 20th. and received in The Netherlands (Europe) on 23rd ! Speedy service! Let UPS try that for $1.5 !!"

Ok, you beat me by one whole day! When I saw your 'testimonial' I decided
to order mine! I live in the Netherlands too. I ordered last
Monday, it arrived today (Friday).

I love my Boostaroo already!

Arie
 

My Boostaroo was shipped on Jan 20th. and received in The Netherlands (Europe) on 23rd ! Speedy service! Let UPS try that for $1.5 !!
I needed an extra boost for my laptop so my twin-daughters (6 yrs old) can watch DVD-movies while travelling.
AND IT WORKS GREAT! Even low freq. sound much better.
Without the Boostaroo the soundlevel 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 ;-)  

I use the Boostaroo for the kids' TV. My 3 kids each have their own inexpensive headphones with individual volume control. When we want quiet and the kids are watching cartoons, we just say "Headphones!" and the dome of blessed silence descends. Also works great for the kids watching a dvd movie on the laptop on a train or in the motel room. Viva Boosteroo!  

I recently bought this product and wow I wish I found it sooner!!! half a year ago I bought a portable dvd play but I could never hear it in the car. But now I can hear it with good clarity. if you have a product you can hear well buy this!!!!!  

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

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.  

I want to install a Delphi XM unit on my
motorcycle with no existing radio...does
the boostaroo make this possible? How can
I make this work?  

We have hooked up to 12 people to one
Boostaroo! We use 1/8th spitter, works
great for groups listening to the
same meditation CD.
If you are thinking about buying one,
do it!! GREAT PRODUCT!!!
 

Well, I have a pair of Senheizer HD270, and I just coulnd't find a portable cd player who would give enuf juice out to make the heaphones 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.  

Using my Boostaroo between an Archos Multimedia and a pair of Sennheiser MX500 headphones, not only increses the volume but significantly improves quality. The acid test being when you take it out of the loop, the sound becomes very lack lustre, almost feeble in nature.
Criticisms are minor, I'm unsure whether it falls into the 'eats batteries' category, and the other being in the UK that the price over here doesn't reflect the price in the USA (£25 vs $19), this however is minor based on the excellent service from mp3players.co.uk. Well done to all concerned, expect more orders, mine is already doing the rounds in work with much reassuring nodding of heads.  

THIS THING ROCKS!!!!!

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. However, I now am ordering my second Boostaroo do to snow covered steps and gravity. I fell down a flight of stairs and landed right on the pocket my CD/Boostaroo was in. The Cd player lived, barely, but the Boostaroo to a direct hit and loosened the wires inside it. It works but only through one side, and we all know Mono stinks!!

I fell very comforatble ordering another one of these and can't wait to get my new one. If you haven't tried one of these fabulous devices then you are missing out.

Get one NOW!!!
 

I do a lot of travelling in a variety of vehicles, of which most if not all have no form of music available (i.e radio or cassette). So with this in mind I purchased an mp3 jukebox to wile away the hours whilst travelling. Although I was generally impressed with the jukebox I was a little dissapointed to find that even on full volume, the output was poor at best. I tried several pairs of headphones with only marginal results. I eventually happened across the boostaroo web site and after looking at it repeatedly for about 2 months and reading the reviews, I eventually decided to take the plunge and order it. When I received it, my first impression was "WHY DID I WAIT SO LONG?". It was remarkable, the increase in quality and sheer volume was fantastic. Also the time it had taken from us to uk was less than 5 days. I would have no hesitation in recommending this product to anyone who has a similiar product with similiar goals. VOLUME!!!!!! Now , finally, when someone says "PUMP UP THE VOLUME!", thanks to BOOSTAROO I finally can. Thank you for an excellent product.  

I have just ordered the Boosteroo and can't wait for it to arrive...I was very impressed by the reviews of the satisfied customers...Thank you so much for making this wonderful product available...Mr. Stevens  

I received my Boostaroo yesterday 4/26/02. 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 CD.s. I think it will also be great hearing the sound on
airline movies. Both me and my wife thank Boostaaroo for your solution to our
problem.

A Boostaroo Booster Backer
Ron Gliot  

Recieved this as a gift about a year and a half ago. What a treat, at $20- this is a tremendous value. Works great with mp3, walkman, cd player and laptop, allows two people to watch the same movie on a laptop!  

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 myGrados 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.  

I saw a review of the Boostaroo at Microsoft's PocketPC site, and realized that it was exactly what I've been looking for. I prefer to use speakers rather than headphones, and this will just the right gadget for my PocketPC as well as my minidisc player/recorder when I connect to my portable speakers.  

This Boostaroo is great! I'd say it's a mandatory accessory for the RioVolt CD/MP3 player, which has a pitiful audio output stage. Turns out, when you pump it thru the Boostaroo, that this thing actually sounds very good. Kudos on a great value!  

I just wanted to know if the volume control on the earphones is necessary, or will you guys be making one with a volume control on the amp?
I have just baught a set of earphones that I really love. I have a casio e-100 and I love the idea you have here
thanks
---Aaron---  

My T.V. doesn't have headphones connector, it only has stereo RCA audio output, so I was unable to connect my headphones to it. I knew about the boostaro in a electronic store, I bought it, I made a cable adapter to connect the boostaro to a RCA output and it works very fine, now I'm very happy because I can listen my T.V. without disturb to anybody else (I can turn the speakers off on the T.V. with a switch).

Now you have another application for this great product !!!  

I purchased the boosteroo recently and I think this is a must have device 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 not is reading like a informercial testimonial I know, but I am truly blown away with the versatility of this 20 dollar gadget. The only feature I would like changed is the battery position. I think it would make the unit easier to carry if the batteries were side by side. But I attatched velcro to the side of unit and placed velcro on my mp3 player and also the dash of my truck. ;-)

Thanks for a great product and Awesome technical support....  

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

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.
Gal.
 

Your product has proved VERY successful in my line of work (military pilot). Because I wear ear plugs while flying, I have been hooking two Boostaroos in series to achieve the desired volume. Unfortunately, during my last trip to the Desert, my Walkman and Boostaroos 'walked away'. I need to replace them, but thought I would ask if there is a more powerful Boostaroo available so that I don't have to connect two together? Thanks for the reply in advance!

LJ  

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

Great product, great price!  

Just a quick note to thank you for sending Boostaroo - I ordered Sunday the 22nd and it is here, in Canada, 4 days later. Truly great service.

I use it with the Creative Nomad Jukebox MP3 unit and which is known for not great battery life and low headphone volume and this will help with both. Volume is better at lower settings.

Thanks.  

I bought a radio system for my motorcycle from MH Instruements which has amplified speakers which uses a personal CD. With the boostaroo the sound quality is outstanding even at 70 mph. Excellent product.  

Pleeesse try and ship today (wed) as someone has stolen my last boosteroo.... and I NEED it badly!!!!!!!! People love them as do I... They're better than sex !!!! When my husband is away I take my DVD portable player (Panasonic LDV75) out to dinner with me. Plug in the boosteroo, put on headphones and watch a good movie. More people come up to me and ask to listen and when they say "WOW" how come you can hear it over all the noise in the restaurant I tell them about the Boosteroo. Most people write down your web address and say they will order. Really, It is the better mousetrap, By the way.... do you have headsets with built-in boosteroos????
thanks
Nicole  

The boostaroo is a neat little package. Its small and neat enough to fit in your pocket and doesn't look too bad either! It does really work. I use it on a pocket pc and it takes the volume well above the level I need to use which is cool for busy roads/tubes. 4 days shipping to the UK was a pleasant suprise.  

This is the coolest thing I ever used!!!
I can't believe it only cost 20$...

THANKS!!!  

I'm an Air Force pilot stationed overseas in Italy. I fly the U-2 reconnaissance aircraft and wear a space suit identical to those worn by shuttle astronauts. I use a CD player on long missions to listen to music, but the aircraft is too noisy. A friend loaned me his Boostaroo and I was very impressed. The CDs are now clear and the sound is great.
Thanks,

I am one of the people who are sick of the volume problems with some of the recent MP3 Players. Since MP3's are encoded at all different volume levels, many songs are much too low at the max volume. After plugging my headphones into the Boostaroo, the volume increased so much that it played all the low recorded songs at the "perfect" volume, and all normal songs at an extremely loud a volume. This is great!! Now I actually have control over my volume. Thanks Boostaroo!  

Two years ago I bought one of your Boosteroo amplifiers/headphone to hopefully cure a problem on my laptop. I couldn't hear the sound very well when playing a DVD during my travels via train. (This turns out to be a technical problem for my brand of laptop when the PC is busy decoding the video stream.)

Anyway, I bought your product to solve this problem and it worked! The sound is significantly louder when using the Boosteroo and it makes the movie- watching on my laptop very enjoyable.

Thanks for the great products!  

I am part of a meditation group that gets together once a month. We listen to a variety of tapes and CD's.

With a single Boosteroo, six splitters and a ten headphone headphone extension cables, we can easily drive 9-10 headphones with no loss in sound quality. At about 12, the sound quality begins to fall off. But that's no problem, add a splitter in front and two Boosteroo's and we can handle 18-20 folks.

Most amplifiers introduce hiss or noise - not the Boosteroo. Great Product.

The only problem we have run into is that our local Fry's has quit carrying it.  

It's the greatest thing I bought in years! It really works!  

We received the Boosteroo as a gift, what a great one! Since then we have purchased several more. We do all of our listening with headphones, and the players we use, DAT-Walkman, Discman, and cassette walkman, never achieve the desired volume. With the Boosteroo not only does the music become more alive, but three people are enabled to join in on the fun! The Boosteroo has made listening to our collection of live Grateful Dead music much more enjoyable. We highly recommend this product.  

I bought the Boostaroo after seeing it advertised on another website, when I was going to buy some speakers for my motorcycle helmet (Bass Monsters @ Equinox). 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 - UK postal systems are very slow but my Boostaroo arrived in just 3 days from the States - again Fantastic. Just a final note for motorcyclists:- the volume and quality of the audio does vary quite a lot between different makes and models of helmet and by how much wind noise is generated by the motorcycle. Persevere though, it is worth it. Hope this helps.  

This will be the second Boostaroo I've owned--I used the first continuously at work, attached to my portable cassette player. 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 awhile without any luck--I'm so glad I found your site!  

Greetings from Sweden!

When I first heard about your product via www.3dsoundsurge.com I got very interested, so I mailed you and asked if I could use your Boostaroo for amplifying my AKG 240 Monitor headphones. You were honest with me and told me that because of the 600 ohm's impedance (these are professional studio headphones), the Boostaroo of today wouldn't help me. That's highly appreciated!

But the interesting part is that you also told me that you are planning to release a Boostaroo that does!

Myself, and about a couple of million PC-gamers out there can't wait for that product to hit the market!

In PC soundcards, we have the same problem with amplifiers that are too weak...

So get on it! You have a HUGE market just waiting for you! At all the gaming "LAN-party's", internetcafé's and other gamingplaces, only headphones are allowed...

Hoping for a product soon! //Mats  

Being an audiophile I had to get this,I will be buying s John Deere riding lawn mower in April so I HAD to have this.This thing works!!I just purchased a just released Sony915 portable c/d player[barely]larger than a c/d have this vel-croed to it and also added a set of Grado SR60 headphones for FAR BETTER sound.Hey.for 23.45 delivered this is a no brainer the boost in power IS IMMEDIATE,there delivery was only 3 days excellent company.Do yourself a FAVOR BUY GOOD HEADPHONES!!!I can't wait to try these out with my new mower LAWNWORK WON'T BE SO BORING!!!Try this you'll LOVE IT!!!!!!!!!!  

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 freinds want to listen to the cd I have they can just plug in!  

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 (though I haven't yet tested how much it will lengthen the life of my regular batteries).

Speaking of batteries: Now how about a gumstick-size lithium ion rechargeable inside a still-smaller-size unit? (It's nice to dream.)

My best to you all for the new year.  

I just wanted you to know that I just
purchased a new Pioneer Portable DVD
player. When I tried to use it on a
recent flight to the Virgin Islands
(w/ my two kids... equals 3 head sets)
I found the sound to be amazingly weak
while in flight! Oddly enough I
found your review in Home Theater while
I was on the plane. I took this as an
omen .... and ordered one ... while I am
in the VI! The perfect solution.
Thanks for a great product!  

Tried your boostaroo. It was last ditch effort at getting cd player heard over built in Honda Goldwing SE stereo system. It worked. Put your product between cd player and tape adapter and music came forth through stereo from cd. Thank you for CD Music on my wing.  

@ COMDEX doesn't have a monopoly on cool gadgets and gizmos. Have y'all seen Boostaroo? This thing kicks! It'll amplify and split the sound from any portable audio device -- making mini-speakers and headphones twice as powerful (by splitting the sound into separate channels). Put that in your favorite hardware MP3 player and smoke it.  

BrightHand (www.brighthand.com) has added the Boostaroo to its list of highly recommended products.

In an article on MP3 music on its Web site, BrightHand states,
"Unfortunately, the Casio Cassiopeia palm-size computers aren't loud enough for most listeners -- even at their highest settings. To address this shortcoming, BrightHand recommends purchasing a specialized add-on device called the Boostaroo. The Boostaroo not only increases the volume, but improves sound quality as well. We give it our highest recommendation."

Thanks for your fine product.

One of my friends has a boostaroo and him and I use it every day on our school bus. It kind of blanks everyone and everything out and it zoomes in on what we really want... THE MUSIC. So if you to were think of stop producing the booostaroos, I have a word of advice... Don't stop selling any of the products.  

Hello Tom,

Two weeks ago you and I spoke of using the Boosteroo with the Top Gear EuroCom motorcycle communications system. This system includes bike to passenger communication, bike to bike communication, and a music interface (CD, radio, cassette). This system overall is great, but it has one shortcoming - the music interface lacked enough volume to make it useful at highway speeds with my type of motorcycle.

I ordered two Booseroo units and this past weekend put them to the test. I went out with a buddy rolling up 800 miles here in the beautiful Pacific Northwest. As promised, here's my findings.

The Boosteroo increased the music volume to the perfect listening level...even at 80 mph! Prior to using your product the wind and road noise overroad the music volume at around 45 mph. My friend has the ProCom unit (more bells and whistles than the Eurocom) with music plus he added a radar detector interface. His Booseroo worked the same as for me, perfectly, without taking away from or interfering with the operation of the radar detector.

In a nut shell, nothin' but raves!!!!!!!!!!

Thanks for making a good product that's inexpensive and performs as advertised!

Best Regards,

Paul C. Sutphen  

I've been using the Boostaroo for 3 days and really like it so far. I purchased the computer model and use it at work. It is very convenient and boosts the sound clarity and volume.

I have 2 recommendations for the next model:
1) longer cord, at least 5'. 3' is still too short.
2) Optional A/C adaptor. I use mine several hours every day and I know I will get tired of going through batteries.
 

After getting my new Casio E-100 PalmPC and 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.  

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

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