It’s unlikely that the Jawbone Jambox will be shoved off its throne anytime soon; not necessarily because it’s the best-sounding portable Bluetooth speaker out there, but because it was here first, and it made a huge splash (in part because, yes, it sounds pretty good).
But I were to bet on a challenger, I might put my money on the smart new UE Boom. Not only is it ruggedized against drops and splashes, but it’s armed with two very unusual tricks.
