The headset was delivered very quickly and was carefully packed. The sales package was very appealing. When you first install - Pairing with the Nexus 5 - there were problems. With the iPhone, however, it worked immediately. At the 2nd attempt with the Nexus to the desired success was then immediately. When operating via Blutooth music quality is slightly worse than with the supplied cable. Petty is really insignificant. You have to listen very very carefully to notice the difference. I highly recommend this device, especially since the price is really attractive.
