Finally, a Jawbone that doesn't hang off the side of your head like geek jewelry. The Jawbone Jambox ($160) is a new portable speaker and speakerphone featuring Bluetooth audio and hands-free capability. It's got stereo drivers for a peak volume of 85 decibels, a 3.5mm input jack for non-Bluetooth audio sources, an integrated rechargeable Lithium-ion battery, and a total of three buttons, or one less than the iPhone you'll be using it with. See it in action.
