My post in this thread ended up being overlooked, so I'm not sure if I should repost or just continue waiting patiently.
Looking for a pair of headphones that are balanced, bass is controlled but gives a good punch, good instrumental separation and something that will bring out the vocals of a song in a warm sense, not sure if it can be described like that. The highs should just be clear, nothing too shrill/harsh. Comfort is important, as well as isolation, but not as important compared to comfort. Cable is preferably detachable. Music: k-pop, pop, rnb, ballad, rock, alternative, blues/jazz, hip hop.
It's only been about five hours since you made your initial longish post. Please have some patience.
Here's the problem/challenge: You have about $200 to $250 to spend on cans that handle both bass heavy and mid centric music and have minimal amplification to accomplish this. On top of that you want comfort, portable, moderate size, non-analytical and a certain type of highs (that knocks out Ultrasones). That's quite a bit to ask. I can't think of anything that will do all that for you.
Closest shot: V-Moda M80 (does not fold up) or IEM's.
