Quick to set up and very good sound,

much better than I expected to experience with the family with other BT devices. My Lumia 820 is just in a desk drawer, 2 rooms away, both doors closed, and the Transfer music to the stereo system is stable and in excellent quality. The sound is really quite close to it on the original CD-frequency spectrum. And since the device via NFC in a brief minute went off without a hitch, I can only say: perfect! Absolute buy recommendation!
