well I wouldn't do much talking but I guess a mic would be cool too. But to be using a mic along with the receiver would be almost impossible i think. lets say i would get some turtle beach x11s? something around the 50-100 price range. Lets say i get the best pair of headphones/headset for that price would i notice any sound difference from my receiver to the USB from the xbox 360? oh and btw my xbox 360 is connected to the receiver using an optical cable.
