I am happy to report that Aliph has come out with a new Jawbone headset. This is something I'm rather happy about because while its Noise Shield technology made the Jawbone the best performing Bluetooth earpiece on the market, it was one of the bulkiest and least comfortable on the market.

Finally, Aliph has solved this little problem WHILE improving the Noise Cancellation technology at the same time! The new technology is called "Noise Assassin", which according to reviews works even better than the Noise Shield. Aliph has also reduced the size of the Jawbone by 50% so now it doesn't make you look like a Borg when you wear it; and lastly they have changed the earhook so it's not as difficult to form to your ear.

Here are what some reviews are saying about the new Jawbone:

It blocks background distractions well enough that I should be able to use my phone at an airport gate without putting it on mute every time an airline agent starts shouting over a loudspeaker.

Wall Street Journal

In my tests of the new, much smaller Jawbone, I stood a few feet from a roaring vacuum cleaner, while on a phone call. The person I was calling could barely hear me with Noise Assassin turned off, but could clearly make me out when I turned it on.

The Verdict: The new Jawbone beats its predecessor from top to bottom in comfort and sound. While the original earpiece set the standard for Bluetooth sound quality, wearing it for an hour felt like exercise to my ear. The gen 2 is much lighter, sits in my ear comfortably and barely touches my face. The clip is slimmed down and covered in leather, a much better feeling than the rubber and metal monstrosity of yore.

Despite these improvements, the Jawbone still has flaws. Incoming sound isn't much better than before; it's loud enough, but the digital crunch found in all Bluetooth headsets is still there. Considering how long Bluetooth has been around, it's a wonder why no one has been able to really improve on this. Also, the new Jawbone only has four hours of talk time compared to the old one's six; the weird part is, it almost has twice the standby time, over 8 days.

The New Jawbone's noise canceling performance was simply spectacular. In one notable test, a caller was unable to tell that I was driving 40mph with the driver's side window down, and in a low gear so as to let the car's engine rev. Indoor fan noise was also completely inaudible.

I could keep going, but I don't think I need to. While the Jawbone didn't receive perfect reviews from everyone, there is one thing that's agreed upon for sure; that the Noise Assassin technology works better than any other noise cancellation Bluetooth on the market.
