Jambox–Jawbone’s nifty super-small, battery-powered Bluetooth speaker/speakerphone gadget–got even a little niftier this week. Jawbone released version 2.0 of the Jambox’s software. It’s available on new Jamboxes, and current owners can download the free upgrade via the MyTalk service. The big new feature is LiveAudio, a technology that’s designed to make sound more multidimensional, including support for binaural recordings–ones recorded using a special technique that only needs two speakers to create a 3D audio effect that can be spectacular. Jawbone provided me with a unit with the new software for review.
