Cingular today began shipping Aliph's Jawbone designer Bluetooth headset as an option for its phones. Besides its characteristic curved design, the Jawbone is touted for its Noise Shield technology. The advanced noise cancellation was developed for the US military and adapts to both the caller's voice and the outside environment: as it can quickly recognize speech and dynamically compare this with other sounds, Cingular says, Noise Shield produces a much clearer sound than headsets that only try to block external sound. Cingular bundles the 14-gram silver earpiece with four earloops to fit different sizes and retails the package today for $120.
