EarFun has done it again: the Uboom L offers more Bluetooth speakers for the money than Sonos, Bose and co. The sound was convincing when tested, but the features are also impressive in this price range. If you can afford it, it's worth buying two and using them as a stereo pair. Remember, however, that you cannot do this in low-latency video mode.
