I just bought 2 of these.. thinking I'd save some money over the more expensive mini speakers.
Compared to the "X-Mini" brand of speakers on sale on Play, these are abysmal. The volume control is a clunky button that you slide to the side, like a normal on/off switch. But this button moves in clunky stages raising and lowering the volume. Very poor control. The bass is distorted. The superior "X-Mini" bass is superb compared to these.
So, in closing.. do yourself a favour and buy the "X-Mini" speakers from Play instead. Yes, they're twice the price, but the sound difference is off the scale. You can't put a price on good sound quality!
However.. if you only need this speaker to upgrade from the worst speaker possible, then it'll do. But like I've already noted, there are better ones readily available here on Play.
I'm very disappointed and have learned a valuable lesson. I'll keep these 2 speakers as emergency speakers, but am just about to purchase the "X-Mini" speakers instead.
