I really like AKG headphones, they generally pack most bang for buck imo, at least around $200 mark. Comfortable and solid. Preferred model depends on what music/material used for, but I particularly like their reference headphones, series K6xx and K7xx. The models are quite similar, just a little different character. Often see them priced around $100-200 in shops.
K702 are my high-end reference headphones with a range of 10-39khz, great for certain tasks and territories, such as ambient music and/or sounds, classical music etc, where there is a lot of detail in the higher registers (and in general). They're razor sharp in the top end. Call them cold, sterile, etc, and I won't disagree. The lack of "warmth", they make up in clarity though. They can get a little tiresome on the ears and brain if used for too long, but for listening through an experimental album or a classical concert, hard to beat.
K601 are my go to headphones. About the same frequency range, but they have a lot more "warmth", more bass and mid, less detailed in the top end (but still very detailed).
Mind that headphones, in general, need to be used for some time to get "broken in", ie to sound as intended.
