Tom Parker’s Boosteroo Headphone Amplifier & Splitter will ‘boost the volume of any portable audio device that uses a headphone jack in stereo without distortion.’

Interestingly enough it also promises to double the battery life of most portable audio players, and will allow up to 3 people to share the same sound source. $24.95 retail.

It’s also being touted as a great gizmo for motorbike riders, and – get this – apparently some U2 pilots have been using it to listen to audible books on long cruises. Er…cruises to where Tom?
