Broke yet another overpriced gaming headset, and I promised a long time ago I won't be buying any more gaming oriented headsets. I know it's a relatively common question here, but what are peoples' best picks for proper headphones? Definitely under 100, but preferably significantly less - I'm not venturing into HD595s or anything higher yet, I just need a decent set of headphones before making a proper investment later.

Only preference is closed cup (for keeping noise both in and external noise out), but I can live without that if the audio quality and price are a good enough quality. No need for a mic.
