Like me, Jawbone has gotten a little skinnier and lighter. And like me, it has a whole new wardrobe. About 50 percent lighter and smaller than the dorkier original Bluetooth version, Jawbone has the same useful noise elimination features as the predecessor. It is being co-sold with AT&T for now and will cost about $130 a pop.

After struggling for much of its early life, thanks to bad product decisions, Aliph, the maker of Jawbone, seems to have turned things around. Its noise-elimination headset has sold enough units for Plantronics to label them as a competitor in a recent conference call with Wall Street analysts. The company has raised VC funding from Sequoia Capital and Khosla Ventures.

I asked founder Hosein Rahman if he is doing a music headphone using his technology, considering how hot the music phones have become. No plans, he said, because of some issues with the A2DP technology. Jawbone 2.0 works nicely with the iPhone and Blackberry, two devices I tried it with, and there’s minimal set-up required. If you have one of those two, it might be worth taking a look. But before you do that, read Walt Mossberg’s big review over on AllthingsD.
