The new Aliph Jawbone Bluetooth Headset not only looks like the sexiest headset ever made, it also uses a military-grade noise-canceling system to deliver crystal-clear audio quality.

The technology used by Jawbone is called Noise Shield, which is developed for DARPA (the Defense Advanced Research Projects Agency). It picks up your voice and not surrounding sounds from the environment, and it also automatically enhances incoming audio.

It comes in red, black, and silver from Cingular, at US$120.
