The latest electronic gadget to show off with LED lighting are these Chinavasion Stereo Earphones. A string of blue lights on each earbud keeps track to the beat of the music to impress your friends or irritate those at work. Lightweight, they can be used for any audio device, portable game system or laptop. You will have to go in with a couple of buds for these as they are available in a 3-pack for $41.13 ($13.71 each.)
