Apparently, a fairly frequent marriage of the transmitter, I found a bunch of reviews about this after I myself encountered it. Through bluetooth they work fine with both the phone and the PC, but there is no sound through the radio channel. The computer sees them and even shows that it reproduces, but there was no sound in the ears themselves. The driver also could not be installed, because you need to connect your ears, but he does not see them. Sent for a refund up. I took the same ones from another seller, the ears are super when everything works)) are excellent for a small head
