Just curious, so you plan on using the headset for voice chat only AND still have game sounds come out through your home theater system?
I do all my PC gaming in the living room too, so I'm trying to see what my options are. I was thinking Sennheiser's PC 360 since it's an open air design with quality cans and microphone. It's an expensive option for just voice-chat, but having the ability to use it during late night gaming sessions for both chat and quality sound is a bonus.
Yes to your first question. I went to WalMart and bought the cheapest headset they had. Works great but it's a double ear one, so i can't hear the game sounds anyways.
