When we caught wind of the Jambox, we knew a game-changer was about to drop.  A Bluetooth-enabled portable wireless speaker that actually delivers on its promise of full-spectrum sound? Something compact enough to throw in your bag, robust enough to take a beating, powerful enough to fill a room with music (or gaming and movie audio), and versatile enough to handle conference calls?

Several emails later, the good people at Jawbone rushed a sample to us for some hands on testing. Out of the gate, the Jambox comes with enough juice to easily pair with your Bluetooth enabled device and tease you with your first song. A quick charge later and it's good to go. From the unboxing experience to the wee hours of a dinner party, with a handful of received calls in between, the Jambox did everything it said it would.

While the Jambox isn't intended to replace existing docking systems capable of stereo separation, you may find yourself so happily unteathered that your other audio devices collect dust. Its pair of proprietary acoustic drivers deliver an impressive dynamic range through an ultra-compact dome speaker that works in concert with a moving-wall passive bass radiator and airtight enclosure. All of which is to say, it produces a damn good sound (from highs to lows you can actually feel on the table) for something so unassuming.

Actually, that's another thing we should point out. The Jambox isn't trying to be all flashy. Sure, it's got a mean looking grille, but you can't get much more ordinary than a black monolith. Designed by Yves Béhar, one of today's foremost product designers, the Jambox is subtle enough to go unnoticed until it's time to turn on the sound. What more could one ask for?
