How can I get the mic sound feedback in my headphone? I bought a noise canceling headphone yesterday and it works perfectly. The only problem I have is that when I myself talk, I cannot hear my voice correctly. I'm wondered if it is possible to enable the microphone sound feedback in the audio output while the headphone is connected? I have a MacBook Pro with MacOS 10.6 installed.
