Product Description The Jawbone 2 is the next step in the integration of best-in-class noise elimination technology with personal design that is both humanistic and minimal. It has powerful noise suppression algorithms for use in the most extreme acoustic noise environments including battlefields and helicopters. The algorithms use Jawbone's two microphones and the VAS (Voice Activity Sensor) to accurately model the noise environment. Jawbone detects when and how a person is speaking, models the noise, and aggressively eliminates it. 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.
Amazon.com Product Description Setting new standards for mobile voice clarity and personal style, the new Jawbone Bluetooth headset by Aliph represents a complete departure from the gadgetry of the mobile headset industry. Originally developed for military use in extreme environments, Jawbone features NoiseAssassin--a proprietary technology that eliminates background noise from mobile phone conversations. Jawbone is the only Bluetooth headset with a Voice Activity Sensor (VAS) that actually feels your speech, which helps Jawbone distinguish your voice from background noise.
The new Jawbone in black.
Widely recognized as the best Bluetooth headset on the market, the new Jawbone is 50 percent smaller than the original, award-winning Jawbone, offer over 4 hours of talk time, and comes with three earbuds and four earloops for a comfortable and personalized fit.
Military-Grade NoiseAssassin Technology Developed over years of research for the Defense Advanced Research Projects Agency (DARPA), Jawbone's NoiseAssassin eliminates real world noise better than competing headset because it's the only hands free device that accurately separates human speech from ambient noise. Unmatched in its ability to remove noise from loud environments like busy streets, cars, crowded cafes, and airports, NoiseAssassin is comprised of two features unique to Jawbone: a patented Voice Activity Sensor (VAS) and proprietary Digital Signal Processing (DSP) algorithms. Jawbone is the only Bluetooth headset with a VAS that feels the speech vibrations from your jaw. This enables Jawbone to capture the distinct frequencies of your voice. Proprietary DSP algorithms work in concert with two powerful microphones and the VAS to accurately model surrounding noise and aggressively eliminate it from the conversation.
Conventional "noise suppression" headsets do not have a Voice Activity Sensor and can only estimate when speech is occurring. This causes performance issues like voice distortion, especially in the presence background noise.
Not Just a Headset, It's Earwear Made with premium materials like medical-grade plastic and fine leather, the new Jawbone with NoiseAssassin combines science and beauty in the most unassuming, yet richly detailed product. Every effort has been made to contain best in class noise suppression technology in a miniature form that is 50 percent smaller than the original, award-winning Jawbone.
The new Jawbone accomplishes a clean and sophisticated look thanks to invisible buttons. Touch-surface technology allows the user to operate switches by lightly pressing the outer shield. Curved and rectilinear to follow the face, the outer shield is lightly textured and inspired by three-dimensional noise abatement surfaces. The infer surface, the one touching your face and creating contact with the Voice Activity Sensor, is gently curved to be ergonomic and comfortable on your skin.
Offering a comfortable and personalized fit, the new Jawbone comes with three sizes of earbuds and four earloops--two sizes of leather and two of slim, which are ideal for use with eyeglasses. Jawbone can also be worn on either ear and with or without an earloop.

Works fine-some suggetsionsNovember 23, 2008 I have used the Jawbone2 for a few weeks and it works fine. Some comments: - it is important to get the little button to touch your cheek, as the instructions say - I needed to bend one of the earhooks to make it work for me. Now it's ok - a positive for me is the need for only two buttons to operate it (both are hidden and separate enough from each other so you don't perform actions accidentally). Especially useful is the ability to change volume without fumbling for a "volume up" or "volume down" button - the only negative I have found is that there is no way to turn it off "permanently". When you turn it off and put it in your pocket or briefcase to exit headset mode, the button to turn it on again can get activated accidentally by pressure in the pocket or briefcase. So you think you are not in headset mode and you are.
jawboneNovember 23, 2008 over all the quality of the communication with Jawbone is great. However as in other reviews trying to get the best "fit" with the ear buds and ear hanger is difficult.
Great Headset.... if you get the right eargelsNovember 22, 2008 This headset is fantastic, but only if it stays on your head, and it stays in contact with your cheek. That is a real problem if you rely on the crappy earhook and rubber earpiece that Aliph provides. It is probably the reason for most of the poor reviews. For those who can make this headset actually stay on, they love it. To address the fit issues that the standard earpiece accessories fail to do, I first tried jabra minigels. I was able to use the jawbone without the earhook, and I raked leaves with it on, no problem. So it seemed pretty good, but I found that the minigel irritated my ear canal after a day, and it did not always feel real stable. I then ordered some eargels for the Plantronics Discovery 925 headset. THEY ARE PERFECT! Totally comfortable, channel the sound into my ear correctly, fit the jawbone 2 like a glove, and I can't shake the headset off no matter how hard I try. It keeps the jawbone firmly connected to my cheek no matter what I am doing. I can't believe Aliph did not come up with this kind of solution. This is what the jawbone2 should have included. If you want the best Bluetooth headset solution out there, get the JB2, get the Plantronics gels, and throw out the earpiece junk from Aliph - you will never need it again.
Horrible ear pieceNovember 22, 2008 The ear piece never stayed against my face so the person on the other end could never hear me correctly.
great theory, poor realityNovember 21, 2008 I don't doubt that the Jawbone is great if you can get it to work. But for a busy person, it is unacceptably flawed. I have read people taking 4 hours to get theirs to work right. For an attorney making $200/hour, that's like paying $800 for a bluetooth headset. I returned this and went with the Plantronics Voyager 510--super cheap and works great! Gonna buy a second since they're so cheap.
