Sennheiser or AudioTechnica.
If you want good sound quality and you buy anything other than these, you likely know nothing about audio equipment.
True, there are some brands which come close, but nothing beats these two, not even the likes of BOSE or similar.
Also a pro tip, if you want good headphones, NEVER buy ones with a built in mic (aka a headset), they *always* have far lower audio quality, even the senns.
Note: these are my current headphones:

P.S. take care when choosing open or closed headphones, mine are open (as seen above).
Open = clearer overall, people around you can easily hear the music, sounds more "natural" as if you're listening through speakers.
Closed = not as clear, much heavier bass, cannot be heard by people around you, sounds as if the origin of the music is in your head rather than around you.
Oh and if any of you ever buy a pair of high end headphones, say $300+, then hook them up to your PC, you should be slapped. At that price, they are designed to be used with an amp, not connected directly to your PC.
