This speaker is seriously a work horse. I used it daily and I often only have to charge it once a month. It features high definition sound and the industry’s longest playtime packed into one of the smallest packages (3-inch cube). It’s powered by a 4-watt, 2-inch driver and topped off with a bass port. The unit also doubles as a speaker phone with a 2-foot range microphone so you can answer or make calls mid-song. It connects with any bluetooth-enabled device (Bluetooth 2.1 and over) or just plug in with the traditional audio cable to start your tunes.
