These work and that's all I can say about them. They connected easily to the two Bluetooth devices I had connected them to and the instructions were clear. However, I was told that the sound quality of the voice is TERRIBLE. They said my voice sounded like I was speaking underwater through a fan. The sound quality of the music played through the headphones seemed decent, although the voices didn't sound like they used to when I heard them. All in all a very disappointing purchase and I regret not throwing the box away until I tried to get it back. I didn't try the wired mode as the only reason I bought them was to use wireless.
