Well anything will work. The more money you spend the better quality. I have a cheap blue tooth it's works but battery just dies quick. I have a very old logitec wired mic from ps2 last time I check I think some games it dosent work any more. But I prefer the eye camera that is what I use and my audio out comes back through my center channel on surround or if u have no surround sound it will come through one channel.(tv) Quality is great it's also has a camera you can use for chat games and soon with there new motion controlls come out you will need one if u care. It has three mics in it and picks my voice up from a decent distance. I dnt really like using blue tooth in my ear. That's why I use the camera But Sony makes a ps3 headset that looks cool it came out with Socom a while ago, and many freinds say it works great. So cheaper the headset the worse battery life!
Also meant write if u want to go over stratagy's cool to don't mind either way no mic cool too just stating it's on so go from there
