i'm in the market for a new pair of headphones that I can take with my to places like the bus or publicly where noise bleed won't be too annoying (this rules out the grado sr-80i's that i would have bought). i'd like them to perform well across all genres with a neutral sound, and be on-ear or around ear, with an emphasis on comfort. i'd like them to be around 50 ohms so i could power them easily although i won't rule out higher impedance headphones because i do have a portable amplifier. a removable cord would be a plus but it isn't necessary.
i've considered headphones by superlux, audiotechnica, and sennheiser, but i'm open to any make or model. suggestions?
