Bluetooth headsets just got a little cooler with the launch of the Jawbone Bluetooth headet.

Designed by accessory unknown, Aliph, the Jawbone is the first adaptive Bluetooth headset with Noise Shield technology, which promises to eliminate virtually all background noise so calls are clearer.

Using technology originally created for DARPA (The Defense Advanced Research Projects Agency) to enhance communications in the most hostile and rugged environments the technology includes an intelligent system of sensors and software, which continuously adjusts-at a rate of 500 times per second-to improve audio quality based on what it knows about the environment.

Jawbone has a perforated shield that curves to match the outline of the face and weighs 14 grams.
