Customer Reviews:
Amplifies very little, AUDIO cuts off COMPLETELY when off
Can't believe the unit does NOT have a Bypass. When amplification is NOT needed, you MUST unplug the unit, and replug your MP3 device directly to your headphones. Very annoying when traveling. I was hoping to be able to turn the unit on and off when needed, but the audio cuts off completely when you turn the Boostaroo off.
Radio Shack had a demostration set up for a boombox. They "rigged" the Boostaroo so that a boombox was playing music, and then they were able to switch the boostaroo on (without unplugging or plugging anything else in) and the audio was much louder. I just can't wait to go back with my return and proclaim Witchery at their store! hee hee
Boostaroo with a Zune 
I bought the Boostaroo with Splitter even after reading some negative reviews about it (and all but 1 of the Boostaroo products). I was hoping for 2 things: to reduce the load on my Zune's battery by putting it on the amp, and to increase the overall sound quality. In addition to the Zune I recently bought a pair of entry level Westone UM1 earphones which are well worth the $120 I paid for them.
There was not a lot of amplification from the Boostaroo that the Zune didn't have already - it just didn't add alot of power.
Worse, there is a constant hiss from the pretty low quality circuitry of the Boostaroo. It did nothing to increase the sound quality through amplification and made it worse when listening to something like classical or jazz by adding that annoying hiss.
I'll be returning the Boostaroo (bought it from Radio Shack) and looking at other options.
Boostaroo 3 
Upbeat Audio T613-BMC Boostaroo 3 Channel Amplifier & Splitter
Design does not allow for any type of mounting. I ride a motorcycle and like most MP3 players, mine can be mounted on the handlebars using a 3rd party mount. If the Boostaroo 3 was designed to at least have an arm strap, it could be mounted.
Also chews up batteries too fast. I don't use is as a splitter, but if the signal is split 3 ways, I would imagine that the batteries would be drained very fast. Should have been designed to use 4 AAs instead of 2.
Otherwise, it is a very good amp and a good way for 2 - 3 people to share a single audio devise.
My first headphone amp.
I have a drawer full of sub one hundred dollar headphones. My newest. Grado SR60s. Pure clean sound for seventy bucks. But could be louder.
I researched headphone amps, I wanted the Grado amp, but I think my wife would kill me.
So after reading the reviews on this Boostaroo. I figured I go to Radio Shack this evening and pick one up.
I've only tried it with my Grados and a cheap pair of Sennheiser 201s.
It worked as promised. The volume of both set of cans was boosted. The Grados sound good, the sennheisers have some distortion. But what do you expect from Twenty dollar headphones.
I'll try it with my AKGs, upmarket Sennheisers, the Koss and the various other cans in the forty to one hunderd dollars range in my desk drawer, and let you know how they are.
A product to avoid! 
First Impression: Looked cool, seemed simple. That's about all that was good about it.
Actual Usage: It required batteries! I don't recall that being in the item description, though I may be wrong. After much hassle of trying to get the batteries to FIT in the compartment and closing it, I was eager to try it. Nothing. It didn't even split the sound. So I tried only one output. Finally, I heard something, but it sounded HORRIBLE. It sounded like my music was being replayed in a ghost movie. I don't even want to TALK about the sound BOOSTING properties, because turning that on gave me nightmares. What ticks me off so much is that you can't use it at ALL without the battery, not even just to split sound without amplifying it. For all I cared, I couldn't even use it as a 6 inch audio cable extension! A waste of time.
Overall: I believe it is pretty self explanatory that, at least, from my experience with the product, anyone who is self-respectful should avoid it. It may have worked for some people, but it certainly did not for me.
