This is the second Boostaroo that I purchased. It isn't quite as powerful as the other, but I knew this when I bought it. Overall, it works well at amplifying music and movies. The amplification is clear, not just louder.
The only cons that I can see are the fact that there is no power switch- plugging the cord into the end turns it on. This is also my other complaint- the cord to hook this to your device comes totally unplugged and can get lost. I have never had this problem, since I am obsessive about checking for all of my cords and cables.
I would recommend this model for an adult who is not prone to losing things.

I bought a good supply of AAAA batteries from Boostaroo and a reasonable price. The batteries last a long time. It is a bit of a bother to remove the connector from the unit to turn it off. But then not having an on off switch keeps the unit small and inexpensive.

This unit takes a Four A battery. Catch that? That's an AAAA battery. What do you think your luck will be when you go looking for more? also, it has no off and on switch. You have to plug it in and unplug every time you want to turn it off and on. And if you don't turn the amp off during commercials, you will eat your batteries up, and not be able to get any more.

I have used this amp for over a year from my cell phone to my sony radio on my motorcycle. This amp cleans up the sound very well and extends my battery life. The AAAA battery last much longer than i expected I would recommend this amp to my friends.

I am very hard of hearing and the boostaroo provides the added amplification for me to hear adequately when I listen from my computer and my iPad.

I use this with my Zune (yes, I'm one of the seven people who own a Zune), and it works great. Not only does the Revolution amplify the audio for my headphones, it allows my "significant other" to plug in a pair and listen along with me.
The Revolution will boost the audio to levels beyond where you need them, so be careful, it's powerful.
I also hooked up my guitar multi-effects processor to the Revolution. Now I can jam on guitar and not bother others who want to hear the TV.
Great product, comes with everything you need to use it right away, and seems like it should last a good long time.
The Revolution will amplify the audio coming from your player up to four times. The extra boost efficiently drives your headphones allowing you to lower the volume of your player, decrease distortion and increase battery life. The amplifier has a uniquely designed circuit that provides clear audio and a more natural listening experience.
