The connection to the smartphone will be manufactured quickly and after the first set up it always works automatically. Tip: I had only a few problems setting up the speakers on my Android phone. You have to enable the visibility of the mobile phone for external devices in the Bluetooth Settings. The volume and clarity of the sound surprised me positively, that fills a room and would loose even suitable for house parties. The battery time is about 5 hours, which is neat. There is a star deduction for the incomprehensible battery level, bringing the queasy feeling with that you do not know after a certain use, whether you can hear a further 2 hours or 2 minutes or previously already needs to load. The speaker may, however, also be taken during the charging time in operation.
The sound quality is also convincing. For the size of the speaker very clean sounds come along. Disconnections or disruptions we could not perceive the extent.
Insagesamt we are very pleased with the performance. A star deduction is available for the desirable indication of battery condition.
