My son went through 3 headsets due to no mic, partial sound coming through ear pieces or not at all. I took his controller apart and located the headset Jack socket. I gently pressed the metal connectors that the Jack plug connect to back into the socket as they'd pushed out a little bit. They'd only been getting a partial connection to the Jack. Ove time they had lost their springyness and stayed pushed out when the headphones had been removed. I put it back together and he hasn't had a problem since. That was 2 months ago
