Problem with the coupling of different devices (S5, S3, S2, HTC Flyer and MacBook) - when was coupled, everything worked just limited. At use with Skype or ICQ zBPC and was not to be thought, it swept only - still had the service again be completely deactivated before listening to music could be made.
The sound was ok, but not outstanding - too shallow.
I would have no apparatus in which I have to occupy myself for hours with the function and look for tricks to make the device meets my needs - I have decided, therefore, to return the device.
As a pure head listening you can use denSBH 7000 certainly, if one agrees with the sound!
