The age-old portable audio question of how to stop your wires getting tangled has been answered by creators of the Split audio, hands free music player. The small coin-sized devices fit unnoticeably into your ears and autonomously stream the sounds without having to sync up to each other (thanks to two high-precision crystal clocks).
Each earbud has it’s own a small circuit board, button cell battery, 256mb memory chip and a 32 bit ARM processor and sound is delivered courtesy of a pair of 6mm neodymium dynamic drivers.
Now here comes the really cool bit: changing tracks is done by chomping down on your teeth and the vibration is picked up by an accelerometer. Obviously they’ll need to connect via cable to charge and transfer songs, and they do this via USB.
