Hello, I just bought a new headset with the microphone and encountered a very annoying problem. As soon as I connected the device into the USB port and the Windows found/installed some random driver for it - I started hearing myself breathe, open mouth, talk. I am not concerned with microphone sensitivity, however. What bothers be the most is that the voice recorded through the microphone goes back into my speaker (headphones). How do i disable this annoying feature? The driver that was installed by windows is called "USB Audio Device" (from the Device Manager under Sound, video and game controllers) and windows sees my headset as "C-Media USB Headphone Set" (from the Control Panel/Sounds and Audio Devices/Voice).

You shouldn't be able to hear yourself breathing. Pull the mic away from your mouth until that's no longer the case. Anyone on the other end will thank you for it. For your problem, go into Volume Control and click "Mute" under "Microphone." If that doesn't work, make sure you're modifying the USB's playback volume. To do that, go into Options -> Properties, and select the USB device and Playback.

Razor, Of course, I would never put my mic that close to my mouth when I actually communicate with someone via microphone. I just put it close for testing. Im sure I can mute microphone, however then I would not be able to use it to talk to someone. I probably did not state it clear enough, but I want to be able to talk to people via microphone, but I dont want my headphones to replay what goes through the microphone.

Go to the mixer controls and mute the microphone in either the recording or playback options. Try each one, I don't remember which one is the right one.

Playback. You want to mute playback, as previously stated.

Thank you, aegis, That helped me a lot. However now it resets the settings every time I reconnect the headset. I guess it is because it is USB =/

You're very welcome Poposchmerz, and I 'suspect' that you are correct about the fact that it's USB resetting the settings.
