For the past three years I've been using a pair of ATH-M50S. They've been great, but they're starting to feel uncomfortable after extended periods of use and I've decided that I'm ready for an upgrade. I listen to music for over 12 hours each day, so comfort is definitely a major concern. Below I have listed the qualities, in order of importance, of what I'm looking for.
2. Sound quality
I primarily listen to indie rock, classic rock, dubstep, and trance. I go to a lot of noisy programming events and regularly listen to music with others in the room, so I'd like something portable with decent passive noise cancellation. I've been eyeing the Sennheiser IE8's. I'd like to keep it under $500. Any suggestions?
