New Accessories Jawbone 2 Bluetooth Headset Black 8 Day Standby Time Patented Voice Activity Sensor Review

New Accessories Jawbone 2 Bluetooth Headset Black 8 Day Standby Time Patented Voice Activity Sensor Feature

• AliphCom Jawbone Bluetooth headset.
• 4 Hour talk time.
• 8 Day standby time. 33ft. Range.
• Eliminates real world noise better than any other headset because it is the only headset that can accurately separate speech from ambient noise.
• Patented NoiseAssassin technology is unique in its ability to separate speech from ambient noise with remarkable precision.

Patented Voice Activity Sensor (VAS) is able to detect very accurately when the person is talking and capture the frequencies of his or her speech even in the presence of noise. Advanced DSP algorithms: the NoiseAssassin algorithms were developed over a number of years for the Defense Advanced Research Projects Agency (DARPA). These required powerful noise suppression algorithms are used in the most extreme acoustic noise environments including battlefields and helicopters. Algorithms use Jawbone's two microphones and the VAS to accurately model the noise environment. Conventional "noise eliminating" headsets do not have the VAS and can only estimate when speech is occurring with software-based Voice Activation Detection (VAD) systems. For these systems to work, the speech must be significantly louder or spectrally different from the noise. These systems fail in loud environments or in the presence of other people's speech. Furthermore, because they can't accurately identify the speech signals, they distort the speech in the process of attempting to eliminate the noise. The result of this distortion is a significant degradation in intelligibility and quality in order to achieve a perceptual reduction in noise. The next step in the integration of best in class noise elimination technology with personal design that is both humanistic and minimal. In the tradition of bringing together beauty and science, the new Jawbone is a miracle of miniaturization and 50% smaller than the original award-winning Jawbone. Every effort has been made to contain best in class noise elimination technology in the most unassuming, yet richly detailed product. No visible buttons: the "invisible button" policy at Jawbone accomplishes a clutter-free look. Touch-surface technology allows the user to operate switches by lightly pressing the outside shield.
