great product 
2008-05-20
My husband and I are seniors. We purchased a portable dvd player for our boat trips, a LG-great picture by the way-but had a hard time hearing the movies with the headphones we purchased. After reading the reviews, thought I'd take a chance,boy, what a difference! I'd say they are exactly as advertised-I'm so glad I bought it.Clear and Loud.Perfect

I purchased the Boostaroo for use with a pair of Sennheiser HD280's. I primarily use the headphones with my PS3, but the PS3's default volume level isn't quite loud enough in some games. The Boostaroo definitely helps in this regard. However, there is some noticeable distortion introduced at medium to high volume levels. I also had to purchase a separate volume control since neither the audio source (PS3) nor the headphones feature a volume control.
Pluses:
-amplifies volume (duh)
Minuses:
-introduces some audio distortion at medium to high volume levels
-no volume control
I'm probably gonna end up returning the Boostaroo and picking up one of those cmoy amps off e-bay instead.
Works pretty well

I have an Archos 504 media player, and it just doesn't put out enough volume for my 53-year-old ears. My Sennheiser PX-100 earphones, which I really like, work fine with my DVD player, but the Archos just doesn't get the job done, even with the volume turned up to maximum. The Boostaroo makes the difference between volume that is not quite high at max, and volume that is quite comfortable a little below max. (Boostaroo claims a 2X increase.)
I bought a CMoy amplifier on eBay, it provides quite a bit more amplification and also features its own volume knob, instead of relying on the volume control of the device it's connected to. I'll probably use the CMoy more at home. However, the CMoy is kind of funky looking and might raise a red flag at airport security, so I'll probably travel with the Boostaroo.
I gave 4 stars instead of 5 because of the battery compartment cover. It has some foam padding that I suppose is meant to cushion the batteries, but it makes the cover very hard to close, and it won't stay closed. I guess I'll end up having to peel it off. A little more quality control would be in order here.
Great,but be gentle with cord 2008-03-20
I heve used one of these for over 2 years connected to a pair of Logitech z2300 powered speakers. The Logitech speakers,which are now only $90 plus shipping on Amazon,become amazingly,unbelievably powerful when the signal is boosted with a Boosteroo.This really helps when using an mp3 with low output(keep mp3 volume down to save battery,hearing and also avoid being arrested).
After 2 years i have now encountered the "bad wire" problem others have noted,but I will still buy another one.This time I'll take care to keep the cord from being moved around all the time,maybe by taping it to the side of the the unit and adding a short extension.
Great Boost for the Money!! 2007-11-09
Works great. I use it when I ride my motorcycle. Even with a very expensive helmet, it's hard to hear your tunes through the noise. This device boosts sound that doesn't bust your eardrums.
Gem of a product 2007-09-28
Provides Portable Audio Players With Much Needed Powerup The Boostaroo is a pocket-size portable audio amplifier/splitter that will give anything that uses a headphone an extra volume kick. The Boostaroo works with all kinds of audio sources (DVD, MP3, CD, laptop, Gameboy, or portable TV)
Works as advertised 2007-07-22
I bought this because I'm a drummer and I play drums along with my iPod through a stereo system in my drum room.
The iPod dock I bought didn't put out enough signal so the amp overheated because it needed to run it at full volume (the music needs to be loud enough to hear over the drums!)
I found this Boostaroo and gave it a try. Sure enough, it works great. I put this between my iPod dock and my amp and it gives the signal just enough boost so the music isn't distorted and the amp doesn't have to work as hard.
So I definitely recommend this product. It works well and amplifies the signal from your portable device as advertised.
Connection problems...design flaw! 2007-06-08
I purchased the Boostaroo at Best Buy a little over a month ago. It's a great little amplifier which does significantly boost the sound, esp an asset with the weak output from my minidsic player.
But this past week my left channel was cutting out. This wasn't the 1st boostaroo I've owned, it's actually my 3rd. And it breaks in the same way everytime, a wire break near the jack that plugs into the audio device. It is not visible, but can be heard easily when sound cuts in and out of one side.
This problem could be solved simply by designing the boostaroo with a removable cable. It would have a jack where you would plug the 1/8'' stereo cable from your audio device into the boostaroo.
This time it is in the warranty period. So I should be able to get another boostaroo free of charge or a refund.
But it will happen again. The short wire (1 foot) and the way it is designed is just asking for trouble. But since no one else has mini portable headphone amplifiers on the market, boostaroo feels it can dupe customers into buying a new one every time it breaks, by the design. Too bad they just cant make a product that would last.
So I really cannot recommend this product, unless you like throwing money away every year for a new one when the wire breaks.
Good, but not good enough for NYC subways 
2007-01-18
I bought this to boost the volume on movies I compressed from DVD to my PSP. (Store bought UMD movies for PSP have perfect volume, but it seems like they're being faded out--low sales). It's nice to be able to watch movies while commuting on the subway, but even the boostaroo didn't boost the volume enough to cut through the rattling, humming, dinging noises on a moving NYC subway train. While I haven't tried it yet, I have to believe it won't work very well to rise above the din on an airplane in flight either.
If you're using it to split the signal of one source to many headphones, it's probably a good buy. But 4 Db is just not enough volume boost to overcome a noisy environment.
Not Compatible with adapters. 
2007-01-11
Do not use this device if you use a 3.5mm to 2.5mm adapter. The standard stereo adapter used to adapt ear buds to cell phone/mp3 players. It does NOT work. Very dissapointed. I tried two types of adapters and both do not work.
