Philips SHP9500 + ANTLION ModMic v4.0 and you get one of the most comfortable headsets ever :) (if you compare it to all that Razer crap etc)Love these headphones!
JhacklerDid some testing(recording), with accoustic n.c. I got it up to 52% of my pc volume without hearing music playing from my headphones, (mic boost on zero). Higher than that, and you will hear music playing on the background when recording. If you are going to use the combo as headset, and you play on volume 10-30%, then there should be no problems. But before I go, friendly advice, don't watch porn on full volume :D
