Depends on your budget and what kind of motherboard audio you have. If you have anything short of ALC1150 and your budget is <80$ you should get the Xonar DGX and pair that with something like the Superlux HD-668B. If you already have good onboard audio (alc 1150/1220) then just the Superlux HD-668B should do or if your budget is below 50$. Oh and as for the mic if you get the Xonar DGX then this would do and also sound way better than pretty much any headset. Else this would be a safer choice since it isn't dependant on your onboard audio which often needs tons of boosting to get to a decent volume level especially with desktop mics (the Xonar DGX handles even desktop mics fine, I know this since I have it and a desktop mic myself and so does 2 other people I know).
