It's been almost a year since Aliph last graced the Bluetooth headset world with its presence, and now it's back with the Jawbone Prime to reclaim the throne. The Jawbone Prime is only a minor update -- on the surface, anyways -- to its predecessor, and in fact the only visible change is a slightly different surface pattern and a minor indentation to denote one of the headset's two invisible buttons. Other than the quite welcome addition of Bluetooth 2.1+ EDR (multipoint connections, easy pairing), almost all the improvements under the hood have to do with the algorithm tweaks of NoiseAssassin 2.0 to improve noise reduction. It's really too bad the original isn't firmware-upgradable (we asked). The Prime will be replacing existing Jawbones at retail for the same old $130 pricetag, and comes in Blah Blah Black, Coffee Talk and Going Platinum, while an "EARCANDY" edition is available in Frankly SCARLET, 'YELLO!, Drop Me A LIME and LILAC You Mean It. Both will be available at retail on May 2nd.
