OK, I decided against going with a surround speaker setup due to neighbors, so now I need a good headphone system. I have roughly $150 to play with. I have an X-Fi Xtremegamer (CMMS 3D) for my sound card and that's it (no amp, etc). I want a headphone that simulates or does surround sound very accurately (I already checked out the Psyko Carbon reviews, not impressed) and doesn't break the bank. It should be good for movies and music mainly, games don't matter too much (except for some surround sound). I have a high quality FLAC music collection of Rock and classical music, so good playback for them is important. My movies usually have 5.1 so I'll like something compatible with them also. Microphone is not important to me, neither are looks. I would also rather they be circumferential (around the ear). Suggestions?
