For the past few years I've used my Turtle Beach PX21's, they're pretty nice, especially with the DSS 5.1/7.1 surround box thingy. It's still great without the DSS though. The mic is amazing, the quality is pretty much studio like. The only bad parts are that my ears hurt from the ear cuffs because the cuffs are too small for my ears, and that if you have the bass up too high, the sound begins to bug out and crackle. But for when you need to listen in on shit, by fucking god, these are some amazing headphones. They have saved me from getting my dick chopped off by some knife happy scrub. They're pretty expensive due to the DSS, but it's well worth it, I'm probably going to buy another pair during this year's Black Friday sale just in case this one will wear out. http://www.newegg.com/Product/Product.aspx?Item=N82E16879459003
I also have the PX3 wireless headset. It's good in it's own way, but I find its lack of bass disturbing. the headset isn't even that great because the battery is shit (10 hours? let me tell you why that's bullshit) I went through 4 pairs all with batteries that lasted maybe 3-4 hours fully charged, and that the presets are just fucking terrible. Even the ones you can find and download are shit. I normally switch to my PX3's when I go take a leak (don't worry, I mute my mic unless you want to hear it c;) and don't want to be left out of a conversation or if I want to be notified of the next round starting. The mic is the same as the PX21's, it has that adjustable long boom mic.
