Since I have yet to find a cell phone headset that doesn’t disappoint me in noisy areas (like my car), I really hope that Aliph manages to deliver on the Jawbone headset. In addition to a mic, it also has a rubber node that listens to the vibrations in your jaw.
By using digital signal processing, the device compares the audio and strips out the noise that didn’t come from you. Pretty cool. Now if I could just get buckets of supermodels to walk around in public with highly noticeable headsets, I might work up the courage to wear one myself.
Bone conduction has been used in several other products, the NTT DoCoMo TS41 phone and the FingerWhisper Prototype.
