I JUST TRIED YOUR NEW AMP,ALL I CAN SAY IS (WOW) WHAT A DIFFERANCE.
I HAD TO TURN THE SOUND ON MAY LAPTOP
ON BOTH MY SPEAKERS AND HEAD PHONES.
IT IS EVERYTHING YOU SAID IT WOULD BE  

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. And by the way, your customer service is tops as well.

Thank you.

I am profoundly deaf and for a long time just used my Boostaroo with an iTouch. Last night I tried it with my Apple lap top and for the very first time in the five years I have owned it, I actually heard things.  

Your products rock! Love 'em!

Happy Holidays!  

I HAVE A BOOSTAROO AND LOVE IT.  

I bought a R234-TV unit and it works great. Thank you for a great product.  

I use all 3 types, the "old" bostaroo (with transparent body) and the new one for portable and also one with the 12 VDC-cords. Bettest in my opinion is the old one, crisp sound with deepest bass! The new one has one big disadvantage: the used AAAA-cells are not easy to find in Europe. AAA are more common and should be planned for next product-update.  

I'm VERY disappointed in the product that I purchased, was informed that this product would BOOST volume by 100%.NOT! Also not as compact as I thought it would be.Will return for hopefully more POWERFUL one. The shipping speed was EXCELLENT.  

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

I recently purchased the Boostaroo Revolution® Mini Headphone Amplifier & Sound Enhancer (R234-2). I wanted to use this with my amazing speaker pillow from Sleepsonic.com. There are times when I prefer my volume a bit louder than most people and this great little gadget did it for me. Now I have it all... great comfort and great sound. Thank you!  

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, and your prices are very reasonable. THANK YOU!!  

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, now have to turn my Ipod Volume DOWN!!!
I LOVE IT
.....The Boostaroo is what I have been dreaming of for 5 years.......  

Received your order, The Boostaroo Is absolutely amazing. Best thing I have spent on my iPod in years!  

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, not need for adapters. I will be getting another one after the holidays to boost my Sirius before the aux. input on my other Harly 2007 Ultra Classic...Bill Fort Lauderdale,Florida  

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.  

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!  

I received you product today, the Boostaroo Amplifier. I am very pleased with this unit, if works very well. I have hooked it up to my treadmill. Finally Led Zeppelin as it was meant to be, it really gives my work out a boost. Thank You.

I got my Boostaroo in the mail today, and I am impressed with how well it amplifies the sound going from my iPod to my stereo.  

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

WOW--Its small and POWERFUL!
No noise or distortion and very high
quality sound and high tech by all means! I use Sennheiser HD 595 headphones- It makes great headphones better! Its Well worth the price!
A more then reasonable price!

I want to tell you, I'm more then deeply impressed by this quality product
and your kind customer care and service. I highly recommend this to anyone who deeply loves music and uses a CD Player, MP3 CD Music, iPod, etc...

There are other amps on the market, but I'm so glad I got this one. It really sounds like your are in the studio or concert. The sound quality is simply Amazing!  

Finally got my boostaroo today! Not that I have been waiting very long, a couple of days, even tho I live in Sweden. But I have been very anxious and nervous. Would it be what I expected it?

Order it. Thats all I can say. If you have any doubts, trust me. It boosts volume ALOT and the sound is still clear. If there is anything I could wish for more, it would be a rechargable batterypack. Except that its the perfect product!  

I just received my Boostaroo Revolution today and tried it out. It's fantastic! I have a pair of very high end, 300 ohm headphones, and with any portable player, the volume was far too low to listen to. But with your exceptionally compact, light weight Boostaroo Revolution, I now have the volume on my player set only half way up. Any more is just too loud. Best of all, it sounds like a high end amplifier. I can't believe the price!
I have been waiting for such a product for years, and your wonderful product is exactly what I was looking for. This is the portable headphone amplifier to buy. Congratulations on a job well done!  

Hi good afternoon I write from Spain where I can find the model R234-MC in Spain
Greetings Vicenç Bassols  

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.



 

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. Now, we can once again enjoy our "in-flight movies". Thanks for a great product. The only downside....the batteries are a bear to install/uninstall.  

I have Boostaroo for my computer and its wonderful.  

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. YOU, Boostaroo, have solved a long standing problem while using my Mac Pro with Windows and staying away from "overkill" -- more expensive amps (Only for one platform!).  

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 expected

Good Work !  

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

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.
 

Just got my Boostaroo and it works great.

I expect you know that the European Union Nanny State, in its wisdom, has decreed that all music players which use headphones have a restricted maximum decibel output. So we Europeans have a miserable maximum volume on our ipods, mp3 players, etc.

You have blown a hole in this legislation - all power to your elbow!!  

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!  

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.  

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.  

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

I have been using my Sportster Sirius radio on my motorcycle with a MP3 player for a receiver for while with a lot of aggravation. The FM signal put out by the satellite radio is so weak, even at two feet away the reception was awful at times. I have been to at least 5 electronics stores and searching the internet off and on for fix for months with no luck. I kept being told, "the only way to pick up the signal is with a FM receiver." By chance I checked with TSS radio and was hoping for a miracle. I got it. The audio out on the sportster has no amplifier, only a direct link to a radio that will then boost the volume. The tss rep suggested I try a Boostaroo. Plugged it into the audio out, plugged my headphones into the Boostaroo and wow! I just wanted to let people know about this because I have found this information NOWHERE. Even folks selling satellite kits for bikes or Sirius themselves. You have a great product and finally cured my problem. Please let folks know about the satellite application. I promise I will let as many people know about it as I can.  

Got one about 3 years ago, and just wanted to say, I love it. Just tonight felt remiss in saying how well it works.  

I am studying medical transcription and there are times when the recording is so low that it is difficult to hear, even with the volume turned all the way up. After searching the internet for something that would help, I came upon your website and purchased the Boostaroo for 39.95. I must say that it was the best 40 bucks I've spent in a long time. The sound boost is incredible, I can hear everything now. By the way, when you make a product that will allow me to understand mumbly doctors, please let me know. LOL. Thank you so much for an excellent product. Sincerely, Tammy Bean  

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

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

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.  

How many times can you say "THANK YOU" to such a great company with super people with such outstanding products?
Well, im doing it again! THANK YOU!!!
A few months ago i left a testimonial about my purchase of the R234 BOOSTAROO REVOLUTION MODEL and how much i loved the improvements they made to it over the ORIGINAL BOOSTAROO which i had been using for several years listening to MP3 tunes and navigation while riding my TRIUMPH motorcycle as i am a full time bike rider and music and bike's just go together, and although both units done the job they had one flaw....BATTERIES!
So after many phone calls to them about what us bike riders needed they listened and delivered!
With the NEW 12-VOLT BOOSTAROO REVOLUTION MODEL R234-MC (so no more searching for AAAA batteries like the portable REVOLUTION uses when your on the road and they go dead and your in a small town at a small mom and pop store who has never heard of such a battery and you dont want to ride without your tunes!).
So after waiting (with no patience...just ask Laura and Chase at Boostaroo!) i recieved the first 12-VOLT R234-MC REVOLUTION they shipped out, and the same day i recieved it i installed it on my bike and am very excited and happy about it as its almost everything i asked for, and the only reason im saying almost everything is the fact that this unit is not waterproof, but here is a few mod's i did to help that matter, the first thing i did since this unit has two audio output jacks and i only use one i put a small smear of clear silicone on one of them to keep water out of it, the other since this is the first production run of them it still has the battery compartment lid on back (which Chase told me will be removed on the later production models) i sealed it off with silicone also, so these few things didnt make it 100% waterproof it did help the water situation but i still advise to remove it in a rain down pour or when washing your bike, another mod i did was to remove the CLA (cigarette lighter adapter) and hard wire it in to my wiring harness on a circuit that is controlled by the ignition key switch so when i turn my key off the R234-MC goes off without having to unplug the patch cable that runs to it from my audio source, also i added to the positive side of the wire a sealed ATM fuseholder and installed a 2-AMP ATM fuse just in case (a not needed mod but since my bike uses all ATM type fuses is why i used that type of fuse but you can use other styles if desired), or if your bike has POWERLET PORTS (which my bike has three but i use them for heated cold weather riding gear and other needs) you can remove the CLA and install the POWERLET PLUG and use it that way or if your bike has a CIGARETTE LIGHTER PORT you dont have to do anything and POWERLET PORTS and CIGARETTE LIGHTERS PORTS are fused already!
These was things i just wanted to do but was not needed to take advantage of this great new product from BOOSTAROO and as the first peron to recieve one and use one i wanted to be the first to give it a write up and big AAAAA+++++!
So again i just want to say thank you BOOSTAROO for another great product and i guess they will be happy not to hear from me every other day now asking "IS IT READY YET!"
but what about that OPTIONAL WATER PROOF VOLUME CONTROL?
So all i can say now when the next version of the 12-VOLT WATERPROOF REVOLUTION MODEL is ready, they better have me on the list or i will be calling!
THANX A MILLION..Mike Ward in KY
 

I just bought boostaroo spliter amplifier and use it on my tv, i'm hearing impaired and this is the 1st product i'v purchased that really works, the volume is great, clarity is great.  

The first thing i have to say is THANK YOU! not just for the outstanding products from Boostaroo, but for the great people you deal with at Boostaroo! A big special THANK YOU to Laura in customer service and Chase in technical support, they are happy to talk with you anytime and answer any questions you ask and listen to your needs and wants for future products for us motorcycle riders as i think they are seeing there is a bunch of us out there and it could open up a whole new or larger market for them. Now for the products, i am a full time motorcycle rider and ride a new Triumph Sprint St sport touring bike and have been using the original Boostaroo for several years now listening to MP3 tunes and navigation in my Shoei full faced modular helmet with speakers installed from my Garmin Zumo 450 Gps and it worked great, but just a few weeks ago i purchased the new Revolution R234 model (just because i like to keep up with technology and improvements) with the optional volume control and it is like night and day compared to the original model and you will need the volume control to turn it down a little because the new model really pumps up the volume, if you ride a bike i highly recommend the new Revolution as you wont be sorry for the small investment for a quality product with such great large results. And as a bike rider i gave them a little input on what we need and they listened, as we need a waterproof Revolution, a optional waterproof volume control and a 12-volt direct wire model (which they tell me a 12-volt version will be available soon and and i cant wait until it does as i want one now! i hope the unit will turn off though when you turn the ignition key off or has a on-off switch as that would be a great feature and a big plus even for the portable battery powered model) But for now im happy with what they offer with no complaints (except for the no on/off switch on the Revolution, but i can live with it) So again all i can say to everyone no matter what you will use it for is "BUY ONE" you wont be sorry, THANK YOU AGAIN BOOSTAROO FOR THE GREAT PRODUCTS AND CUSTOMER SUPPORT TEAM!  

I recently got my Boosteroo, and attached it to the side of my helmet, just above my MP3 player. What a difference ! Now I can hear my tunes at cruising speed... Nice little device...Dennis, Red Bluff, Calif.  

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.  

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 !  

IF YOU OWN A LATE-MODEL LAND ROVER PRODUCT YOU MUST PURCHASE A BOOSTAROO!!
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!  

I stumbled upon this site almost 8 months ago. I decided to try the monthly drawing thing and thought, "what have I got to lose?" A few months later, I won! I was very excited; I got my amplifier just a few days after I received the email. 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 may like it.

-Griffin Haskins, MI  

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.  

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 recieved my Boostaroo in only 6 days !
 

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.  

i am writing this to tell you how pleased i am with the boostaroo i bought just before christmas last year. why you may ask did i wait so long to write this?well the timing came with a change of batteries, as amazing as it seems the first time i had to do so! of course you may say i never or hardly ever use my boostaroo; not so! in fact i use it every day (well 5 days a week) in work for about 6 hours at a time. its incredible. my only complaint is the size of the battery it uses AAAA, maybe you can get them easily enough in the U.S. (i did look for them in San Fransisco (great city by the way :) )a few months ago but couldnt find them) but here in Ireland they are impossible to come by until that is you look at a 9v duracell battery.it contains 6 of them. so impressed was i by the boostaroo i bought a second one soon after my first just in case my first one broke; it didnt. 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 (of 256kps or more) while increasing its volume.some things in life are just brilliant, take a bow boostaroo!

ps. to the makers of boostaroo, is my battery life a record? just curious. i read somewhere that batteries last approx. 20 hours. obviously thats not true.  

I have a profound hearing loss and finding a MP3 playler that is loud enough for me to hear was a hit or miss. I can't tell you how many MP3 playlers I have bought and had to return because I could not hear the music on them. Even the cool MP3 playlers like the ZUNES, IPODS, AND THE SONYS. 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 $49 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!!!  

GREAT PRODUCT...I USED MY BOOSTAROO THIS PAST WEEKEND TO CONNECT MY DELL LAPTOP TO A 400 WATT HOME STEREO SYSTEM. THERE WAS A NOTICEABLE DIFFERENCE IN THE VOLUME AND SOUND QUALITY...I'LL RECOMEND TO ALL OF MY FRIENDS...THANKS

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 SportaPro Headphones in the Gym and I couldn't be more pleased and happier with this great invention. I'm sure that the Koss Headphones help as well since I have not been able to find any better sounding portable headphones anywhere. They sound Very Good without the Boostaroo; but, they sound FANTASTIC with it. Plus, the battery has literally lasted me over a year in both amplifiers. I just make sure to un-plug the Input Cord when I am not using it, so that turns OFF the Boostaroo Power. Now, I need them to go and design it SMALLER so that it is easier to attach to my waste-band-clipped iPhone 3G in a Contour Design Case. Or, better yet, design it INTO or INSIDE OF the Koss SportaPro Headphones. That would be the ultimate product for me. Thank you for a GREAT PRODUCT!

A VERY SATISFIED CUSTOMER,

Bill  

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

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

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.  

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.  

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.

Devan from London, UK and very happy Boostaroo customer.  

Best money ever spent. I purchased a garmin nuvi for my car for gps and mp3 purposes, but the volume output from my garmin into my car's headunit 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 with a little more punch from my stock speakers, and hopefully with no distortion or static.

I ran across this usb connected boostaroo aux 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 (got from radio shack, 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 nuvi on pause, cranked the volume to listen for static.. NONE. I'm very impressed.

Now I have all my electronics (radar detector, garmin nuvi, and my boostaroo all powering up with my car's ignition thru a 3-way cigarette lighter spliter... 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!  

I have received the units today and the Boostaroo Revolution performance is great with my Sony PSP & other MP3 players.

Satheeshkumar  

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.

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

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.  

G'day from Thailand,

I'm very happy to let you know that our order which left on the 29th July has already arrived in Thailand on the 4th Aug. Thanks for your speedy service both on the web and the order.  

I need to increase the audio level from my iMac to my Crate FexWave 65/112 guitar amplifier's CD input jack. I think your Boostaroo Revolution® High Fidelity Portable Headphone Amplifier & Audio Splitter Model: #R234 will do the job but the expensive AAAA batteries are the deal breaker. Let me know when/if you develop an AC/DC version.  

I love this little Amp!
Get One!  

I am a retired 60 year old school teacher. I was having trouble hearing my music as I mowed the lawn. I am hard of hearing and have to wear hearing aids. I purchased the Boostaroo 3-Channel Headphone Amplifier and WOW! This thing is great with my portable CD player.  

I don't see the use I would like to see for your product. Perhaps it can be used this way and you can tell me.

My hearing loss interferes with my television enjoyment. To crank the volume up on the TV for my listening, I blast out other viewers because they DO NOT have hearing loss.

So I'd like the ability to amplify ONLY my audio experience leaving the speakers of the television at normal audio levels for the other viewers. Is it possible with your product to split the audio this way so that only my audio is amplified?  

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.
Thanks.  

ALL I HAVE TO SAY IS, BUY ONE!!!!  

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!  

I recently bought the Boostaroo Revolution for my Archos 605 wi-fi. The Archos 605 wi-fi 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.  

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'.  

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 dissapointing. I searched and found out that a headphone amp was made a mad dash for a local retailer who carried the Boostaroo. WHOW!!!! Now I got some punch in my tunes. Great product!  

I JUST RECEIVED MY BOOSTAROO MINI-AMPLIFIER. IT WORKS JUST AS ADVERTISED. I USE IT IN CONJUNCTION WITH A BLUETOOTH ADAPTER (LOGITECH) AND BLUETOOTH HEADPHONES (MOTOROLA S9). I RIDE A MOTORCYCLE AND HAVE BEEN UNABLE TO HEAR OVER THE LOUD MUFFLERS WITH STANDARD VOLUME. WITH YOUR AMPLIFIER THE SIGNAL IS CLEAR AND STRONG.  

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! (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've been using your products for 20 years.  

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,

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!
