Jawbone Big Jambox

The Jawbone Big Jambox isn't quite the equal of the Sony SRS-BTX500 (Est. $300) for sound quality, but its battery life is far superior -- up to 15 hours, as opposed to six. Like the Sony, it has a speakerphone feature that reviewers say works very well, and its controls are very easy to use.

Good sound quality; Excellent battery life; Useful features

Bulky; No carrying case; Problems with pairing

Jawbone Jambox Bluetooth speaker

Review It's a chunky little fella, the Jambox, and when you look at it, it's not instantly clear what it is. Jambox is the creation of Aliph, the makers of the excellent and stylish Jawbone Bluetooth headsets, and the company's noise-cancelling smarts come into this product, too.
