Ever wish you could crank up your iPod to drown out a noisy environment? Sure there are scores of headphones that will seal out or electronically ‘remove’ background noise, but there’s still a limit to your volume control.

Meet the Boostaroo Revolution high-definition portable amplifier / splitter. The Revolution increases volume by up to 400% while providing high-definition audio separation, all with less than 1% harmonic distortion. The Revolution’s patented circuitry separates your audio signal into three distinct channels, creating a surround sound effect. Also touted to conserve battery life in your audio device by taking the pressure off its internal power-draining amplifier. Recommended for use with computer speakers, as well as headphones. If you’re using your iTunes to get the party started, Boostaroo can help you crank it up!
