At just £30, the SW50 seems to be a bit of a steal. This 7cm-wide speaker – small enough to slip into Darth Vader's clutch bag – pairs with any Bluetooth A2DP device and deals with hands-free calls too. Battery life is a rather lacklustre three hours for music and four for calls, after which you'll need to recharge it via micro USB. But that's the only blot on its copybook – until you give it a listen, that is.
SoundWave SW50: small sound
It's small. And it sounds small. It does manages to avoid the "drunked wasp in a can" noise beloved of smartphones, but don't expect to turn your park social into a P-Diddy bump and grind-a-thon as bass is nigh-on absent. Still, it's a doddle to use and at least voices come through clearly.
SoundWave SW50: simple
With no volume control of its own, the SW50 relies on the level at which your Bluetooth-connected gadget is outputting – basic, but nice and simple.
