Aliph ships their cool looking Jawbone mobile phone headset.

Apperently the technology behind the Jawbone is based on breakthrough military-grade technology, the Jawbone adjusts and optimizes both incoming and outgoing sound to achieve exceptional clarity in any environment in a manner previously not achievable.
Inside Jawbone, an intelligent system of sensors and software adaptively enhances the audio signals using a three-stage process: first, a voice activity sensor detects the vibrations produced on the cheeks by speech. Meanwhile, two microphones capture and then subtract unwanted and disturbing background noises. Finally, Jawbone dynamically enhances the incoming audio, allowing it to stand out clearly above the clamor of your background. Sounds cool, anybody tried it yet? email us.

The Jawbone sells for $149.95 on the Jawbone site. Most Motorola, Nokia and Sony Ericsson Phones are compatible.
