I have no idea what I'm doing, so if someone could explain why they're suggesting what they're suggesting, that would be awesome.
I want to get a pair of headphones that have clear directional audio in the source engine, particularly Team Fortress 2, and good performance in Counter-Strike never hurt anyone. I currently am using a $10 logitech usb headset, and I can tell where things are, but I can't tell what. Everyone else on my competitive team (yeah, competitive tf2 does in fact exist) can hear and distinguish between all the classes when they are running on the other side of a wall, while I just hear noise coming from that direction. I've used good headphones in the past when I was into a school radio station, so I know its not that I just have ****ty ears.
I don't need a mic, since I'm set on the AntLion modmic 2.0. I want to know what pair of headphones I should get (cheaper is better, I'd like to stay under $100, but I could do $200 if it would make a significant difference) and if I should pair that with a certain sound card. I can do any sort of modding/installing of things, but I'd prefer to not have to take a dremel to my headphones. Not having to mod them is worth ~$40 to me.
I've read through other threads (what someone using a forum intelligently?), and the Q701s seem good, but I couldn't find anything that was TF2 focused, most of it looked at CoD or Battlefield or superbasssssss for cinematic RPG scenes, and they're a bit above what I want to spend.
