I recently purchased a Plantronics GameCon 380 headset for gaming, mostly for LOTRO. They have 3.5mm plugs for headphones and microphone. When plugged in, I am only hearing background (environmental) sound, not speaking voices.
If I pull the plug halfway out, I can hear everything.
Before I return them, can anyone explain why this is happening? Mostly, I want to know if the problem is with the headset or the computer. I have 2 computers, and the headset acts the same way on both computers, but both computers have the same case, so I'm thinking it could also be an issue with the audio jacks on the case.
