My luck with Bluetooth headsets has not been good but I am still anxiously awaiting the new Jawbone Bluetooth headset ($119.99) which should be released soon in silver, red, and black. You can send the company, Aliph, an email to pre-order. They are offering free UPS Ground shipping to any customer who emails their name, address, and color preference to firstname.lastname@example.org by January 15th. This headset will work with any Bluetooth enabled phone.
Using an adaptive sound technology developed at Lawrence Livermore Labs, the headset incorporates two microphones and a unique voice-activity sensor. When placed against the cheek, the sensor actually detects the vibrations produced by speech, rather than picking up the sound from your mouth. The Jawbone also uses adaptive microphones that capture and cancel out background noise, so incoming audio also is enhanced and adjusts to the varying noise levels for your location. You can see a video demo of this technology by clicking here.
