Isn't it a pain when you have to look at your earbuds to work out which one's left and which one's right . Or you find that you've had the wrong phone in the wrong ear . Well the Japan Science and Technology Agency ( JST ) has a solution with their Universal Earphones. Â Using a proximity sensor the Universal Earphones automatically detect which ear each phone is in so that you'll never have to worry about your stereo seperation again. In addition if you share earphones (something that all teenagers seem to do), then the phones will detect this do and put a full mono stream into each earphone rather than just a single channel.
