We actually just upgraded our console and are using a Plantronics wireless headset. Worked great for about 2 weeks then all of a sudden it was doing the exact same thing. She said no matter what they did on the console they couldn't hear anyone through the headset. I went over there assuming they had just put the audio on mute on the computer itself accidentally because of the hotkey on the keyboard but when I showed up it was working correctly. They ended up power cycling the headset dock and it came back up. Almost like the drivers for the headset crashed and never started back up but power cycling it got them going again. We only use the one console so I can't say if it's a common thing.
