Do you leave your iPod cranked up all the way and still want it to go louder? Years of standing right next to the speakers at Journey concerts has left you half deaf, and in order to finish the job you'll need more than the iPod's paltry volume output. The Boostaroo Revolution is a high definition splitter and amplifier for portable audio, and it can boost your volume by up to 400% without distorting your music. Once you get used to listening to music at that volume, you'll wish there was a Boostaroo for your family and friends, as you'll struggle to hear what they're saying without some form of amplification. Just make sure you hook this thing up to headphones and speakers that can handle the juice, as just because your music player can pump out tunes at insane levels doesn't mean your white earbuds will suddenly sound like decent headphones. Hop on the fast track to deafness, only $60 and available now. — Adam Frucci
