The headset looks very valuable and is well made. But that's also the downside, because it is hard and pushes the head. The sound is just bad if connected via Bluetooth or directly using the supplied cable. My "approve" Bluetooth headset has the same poor sound.
Positive is the Bluetooth pairing. The device is also coupled Once registered the next time immediately. The range is only 5 meters, the sounds are pleasant and loading is quick. I sent the headphones back.
