I just use a cheap Wal-Mart headset. Nothing special. If it works, its good enough for me. If high quality is your style, then you may want to google "high quality headsets" or something of that sort.

Don't you think any headset with mic will do?

depends. quality of the speakers for one is a thing I use to make the best buy. functionality is another. clarity of the mic as well. not to mention how well the sounds are distributed, IE- left sounds clearly coming in from the left speaker, etc.
personally i think is DOD:S there are too many explosions and gun shots and stuff like that. You don't really need to listen closely. but like in CSS a headphones really help.
