I've tried everything, but I could elicit no sound system. The Speaker is indeed shown as coupled, but subsequently displayed as "not connected". Even with an additional Bluetooth dongle, it did not work out. The Quälität the case is anything but cheap and seems to have a great finish. Unfortunately, the connection is only possible using the supplied jack cable. But I can not use .... Device goes back unfortunately. Would like to see a notice in the item description would be that there may be with Win8 systems, talk to internal device Blutoothadaptern problems!
