* Jawbone 2 Voice Activity Sensor: VAS is able to detect very accurately when you are talking and capture the frequencies of your speech even in the presence of noise.
* Advanced DSP Algorithms: Noise Assassin technology is unique in its ability to separate speech from ambient noise with remarkable precision. Jawbone 2's Noise Assassin is able to achieve this while other headsets cannot. The Noise Assassin algorithms were developed over a number of years for the Defense Advanced Research Projects Agency (DARPA). The algorithms use Jawbone 2'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.
* Smaller: The new Jawbone 2 is a miracle of miniaturization and 50% smaller than the original Jawbone.
* Medical Plastics: Constructed with ultra-smooth medical-grade plastic, the new Jawbone 2 also comes with optional fine leather ear-loops. The outer shield, curved and rectilinear to follow the face, is lightly textured in a sound-reflective progressive relief, a three-dimensional texture visually representative of noise abatement surfaces. This unique surface becomes animated as light creates highlights and shadows when worn. The inner surface, the one touching the face and creating contact with the Voice Activity Sensor, is gently curved to be ergonomic and comfortable on the skin.
* No Visible Buttons: The "invisible button" Jawbone 2 accomplishes a clutter-free look. Touch-surface technology allows the user to operate switches by lightly pressing the outside shield.
* Includes: 110-240 volt AC travel charger, USB cable, 1 Earbud, 1 Earloop.
* Bluetooth Hands-free profile(HF) and Headset profile(HSP) are supported on this Bluetooth version 2.0, class 2 device for fast, secure connectivity up to 30 feet away.
* Aliph factory original one year warranty applies.
