Unfortunately, you can not bring the sound over which this portable Bluetooth speaker has it, even though he (W 2.5 W + 2.5) output is equipped with "only" 5 watts with a text. I was really quite surprised. Especially when you want to let it rip right times, the unit is quite convincing. Workmanship and design are in the green zone and the splash capability brings its benefits. I can connect it in seconds with my Sony Xperia Z via the NFC interface, simply hold the device together on Logo and off you go, great! Unfortunately, there are also two disadvantages, which I would like to report. Charged is the speakers with an AC adapter, which has a special connector. Why have not taken a normal USB plug here? So one would have, just for the holidays, to save one of these läßtigen parts again. Then the battery is firmly installed. With the demise of the battery is then also over the loudspeaker. Unless you only operate it to the power supply, but then probably the term "portable" misplaced. Otherwise a successful instrument, which I give 5 Stars despite the disadvantages. The party can start.
