All fair points. I don't use my headset all the time, and the mic doesn't seem to get in my way too often, but YMMV. Overall I like mine, but I'm willing to bet your headset alone is betting quality than mine.
I have a good 5.1 surround sound speaker set up when I don't need the headphones, so I didn't have to worry about getting the BEST ones, although mine are still pretty good. Looks like my headset was quite a bit cheaper than Campbells (although if he got it on sale, who knows what the price would be), so his sound quality is probably tons better than mine. I wanted wired though, cause I don't like having to charge the things. The only thing I use that's wireless is a mouse. So who knows, maybe the wireless adds a lot to the price in order to keep quality up.
I never hear myself over teamspeak so I can't talk about the quality of the mic. I've never had anyone complain, but if you've found any problems my voice quality, use that to make a decision.
Like I said, if you get a cheap 30-50 dollar headset, the mic will probably be in an annoying place and the whole thing might fall of your face or something. Get something in the 100+ range at least (Or at least would be at that price if it weren't on sale). I think I bought mine for 90 bucks with the price originally around 140 or something.
