jawboneOn the other end of those irrationally disturbing bone-vibrating cellphones that came out earlier this year is the Jawbone headset, which uses the vibration of facial bones (as well as a microphone) to pump up the voice of the caller, while quieting the annoying background noise. If it eliminates all the absurd noises that come through when people talk on headsets we'd be really happy. Of course the next step is simply to implant a sensor directly into the jawbone itself, which would totally blur the line between headset users (who still get the occasional odd look on the street) and those people who incessantly mutter to themselves on the subway. It's designed by Aliph and will cost "under $150" (which means $149.99)
