Don't use a headset/mic combo. Get a headset that sounds good. Get a mic that is clear. 2 separate pieces of hardware. The microphones built into most webcams for video conferencing are the best I've found. I use them daily for voice chat (games) as well as tele conferencing at work. it is absolutely amazing how clear webcam mics are. I currently use: Microsoft Lifechat LX-3000 headset (wired usb)..it has a mic built in but the mic sucks. headset sounds great though. Logitech - QuickCam Communicate MP Webcam
