Braven, which used to be called Spar, has just introduced a new Bluetooth speaker range that aims to differentiate itself from the others out there thanks to a couple of uncommon features. All three can be daisy-chained to provide stereo or surround sound, and they can also be used to charge phones or other portable devices through their USB ports. The wireless range is Bluetooth's typical 33 feet, and the auxiliary port also allows connecting other sources.
