Don't call it Jawbone 2, Aliph's Jawbone sequel is the company's new flagship product, with the old Bluetooth headset being put out to pasture to make way for the new hotness. The new Jawbone is 50% smaller than the original, and includes "NoiseAssassin" technology, a followup on the noise canceling tech of the original. There's a faster processor on board to handle heavier signal processing duties for canceling out ambient noises better and faster, along with that Voice Activity Sensor which lets the Jawbone know when you're talking so the rest of the time can be noise free. A new fast charge battery can suck up 80% of its capacity in 30 minutes, but the overall battery life is lower than the original, with 4 hours of talk time and 8 days of standby. The whole unit weighs in at 10 grams, and is available now for $130 at AT&T retail stores and online at Jawbone's site. Initially it's being offered in black only, but silver and rose gold (pictured after the break) versions are coming soon.
