The Bluetooth pairing (HTC, iPad, iMac) done quickly and easily.
Coupled I have the speakers with the iMac,
the music volume can be controlled via iTunes or via the buttons on the top of the speaker.
The sound is surprisingly good for this speaker size and convinced me.
Not only bass heavy music, but also quieter sounds are very well placed again without buzz or creak.
Very good I think the music of micro SD cards or USB sticks can be played.
The radio function, where the radio reception (almost) perfectly convinced.
