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. Specifications

 This Thing is an Expensive Junk Show November 17, 2008
A friend did some research and the industry reviews said best of market for this thing. Well in the real world, junk. I bought a cheap Plantronics and it did the job clearer, better and with a better fit, largely due to the better design.
 Surprised November 17, 2008
I have never been happier with an earphone. After reading some of the reviews I was kind of leery, but I was also desperate. I needed something that would cut out the background noise in my work environment, so I could talk and participate in a series of conference calls.
My work environment has racks of computers with multiple fans and a large air conditioner. A lot of times people can hear the background noise and on a conference call I'm sure this would be rather annoying.
I tested a couple of times with friends and they couldn't tell I was in the computer room. In fact some of those that I called thought I was on a late lunch or something since they couldn't hear the background noise. During the first conference call I checked with a friend and they said they couldn't hear anything other than my voice.
Like others I had problems with readjusted the headset. You press on the top and you hang up, so you have to be careful about this. For the most part though it doesn't require readjustment, it just takes some getting used to have it on your ear if your not used to having an earphone in.
The other concern was whether it would stay on. I can recall only once where I ran into a problem and it just didn't seem to want to stay put. This is one of the times I hung up on a caller, while readjusting it. I'm also a big guy so this may be one of the reasons why I never ran into a problem with the mic not touching my cheek.
So if they could fix the way you hang up on phone calls this would be perfect, but for the most part I just put it on and I'm set.
Four stars because they have a flaw in their design that should be easy to fix and should have been picked up during user testing.
 Jawbone II, Bluetooth Earpiece November 17, 2008
Best Bluetooth earpiece I've had... out of 5 different manufacturers in the past 6 years.
Noise cancellation is great... I can still be heard in my convertible with the top down!
Great, but... November 16, 2008
The sound quality is *very* good, but only if you set it up and use it correctly. Not crazy about the controls; too easy to actuate them when you don't mean to, like when you are adjusting it in your ear, in the middle of a call in progress--it's too easy to hang up! Mine came without a medium-sized earbud. I almost sent the unit back because I couldn't get it to work right, until I realized I only had large and small earbuds. I contacted the company, and they did send me a medium one (no charge); now it works well. Also, you have to wear it correctly. The front part *must* be touching your face, and I have a beard, which makes it difficult; if not, the other party has trouble understanding you.
Overall good, but only if you understand you have to fiddle with it to make it work right.
Sound, design, efficiency-Jawbone excels! November 16, 2008
I found my new Jawbone after a grueling day....it was in place in my ear, of course, but so light and unobtrusive that I forgot I was wearing it until my girlfriend called, and her voice clear and sweet reminded me what a terrific piece of technology this is!
