The bem wireless Mobile Speaker let"s you hear what you want, when and where you want, without the old limits of space (put it anywhere), time (pair & play in moments), appearances (six cool or cute colors), cost, or size. In fact it measures barely 2.5in cubed - That is smaller than a tennis ball, so when you bring it to the court, it"s less intrusive than your water bottle. It sounds great! Rich, precision tuned, kind of hard to believe, for something so conveniently connected via Bluetooth, with your smart phone, iPod, iPhone, tablet, etc. Includes 1 mobile speaker, mini-usb cable, 3.5mm cable, USB AC Adapter and user guide
