Sony Ericsson just came out a motion activated headphones MH907. It uses your body heat signature to turn on and off a specific function. For example, if you put both speaker buds in your ears, it will automatically start listening to music; and if you take one off, it will pause. So how does this work?
Well, the Sony Ericsson MH907 uses capacitive technology just like your touchscreen smartphones. These tiny heat sensing capacitors are lined in the ear buds. Watch the video demonstration of the Sony Ericcson MH907.
Specifications: sensitivity <1%, omni-directional, speaker driver 9.2mm
