The Braven 650 portable speaker is more than just that -- it’s also a portable phone battery, charging your mobile if you’re not near a power point. It’s as easy to use as any Bluetooth speaker could be, and it sounds pretty good too.

The Braven 650 is expensive but then it also offers the most comprehensive set of features we’ve seen on a Bluetooth portable speaker. It has double the battery life of most competitors, audio output and the ability to charge your phone, all of which are genuinely useful additions. ...

Apple doesn’t currently support Apt-X in its iOS devices, so you could certainly save some money by opting for one of the less expensive models in the Braven range. However, the sturdy design, robust sound and long battery life of the Braven 650 make it one of the best pocket-sized portable speaker systems currently available.

It may not be as loud or as bass-heavy as the Jambox, but the Braven 650 does sound very nice indeed. We love the construction quality. It's built better than the Jambox, and that thing is tough enough to survive almost anything. So the Braven really should last and last and last. The speakerphone quality is another bonus, and overall we can fault it for quality. Our only real concern is the slightly low volume output, and the cost of buying one, which is pretty substantial.
