I know you say you don't want one that is using the red and white cables to capture audio, but I'm recommending one anyways and I'll explain.
This headset is cheap and works really well. I've never had an issue hearing someone while using this headset on the PS3, though on PC when used through Steam, all the options have to be changed on a game by game basis, and that's an issue with Steam, not with the headset. The headset allows you to change game volume and chat volume seperately. The USB when playing on the PS3 is for chat only while the red/white audio hook to the tv to allow you to hear the games music and sound. The red/white audio cables have male on one side and female on the otherside, so you can still use the inputs you're using to record your gaming footage while listening to the game through the headset.
I don't exactly know how long the cord is for the headset, but maybe 12-15 feet?
