The prototype ReGEN: Yo-Yo Powered MP3 player device, no battery and no adapter needed. A 10 to 12 tosses will power you music for an hour of continuous playback. The wireless headset enables you to play with your music without missing a beat and the solid-state memory ensures a skip-free listening experience. Just wonder how the LCD will be built to withstand the rigors of regular yo-yo tricks and stunts, I think that the LCD will be easily break if we accidentally hit something during the tricks and stunts.
