Not my claim

For the price that this headset will cost, I have much more quality expected. The sound quality of the headset is already exceeded by my 08/15 15 Headset, the comfort is just times as moderately okay, the headset fits a bit tight.
The Mic function works under Mac OS 10.9. not. A solution to this problem you can get on the official site,
but what is there, is completely trivial and does not work, caused to even more problems. It is orphaned to the sound options, and should under "Sound -> Input" as Mic Select the headset from. The audio playback function, crashes and can only be restored by a new couple. The Kopplen but runs smoothly.

Since I do not really just wanted to use for eg Skype sessions the headset, there is no me here definitely sound quality.
Haptics and material quality are, as far as I can tell, satisfactory. Again, I would have expected a little more stability and usability for the price. Overall my headset occurs quite wobbly. The buttons are, in my opinion, a bit too hard to use. You can feel the touch of a button considerably the pressure on the ear.

Untested Features: NFC, range, microphone (ohh miracles), coupling to multiple devices, functionality in Windows (Mac bugs have given me no domestic situational headset.)

Test Time: 10 minutes, then immediately wrapped frustrated again because it does not meet my requirements, which are not even really high. As mentioned, I'll use a current ~ 15 08/15 wired headset of much the same design.
For the evaluation here I needed more time, than to test the device.
