Hi. I purchased the q701's in conjuntion with the m-stage a couple of months ago to replace my m558/fiio e7 combo, loving them so far. What I'm after now is a cheaper set of fullsized cans. Say around the $150 mark, closed back, somewhat portable, and have an overall different sound to the q701's (something bassy perhaps for the gym) Also the impedence has to be low, as I don't want to be shoving an amp into my pocket along with my phone at the gym. I'm leaning toward the ATH-M50's (I like the white version, also the silver version is sweet too) Before I make my final decision however, I would like to read some alternative suggestions if possible. -Cheers.
