It depends on what you like for sound/music. I've got a few pretty decent pair, when I want to hear more bass, I'll go with my Jays A-Jays 5. I used to have a pair of Shure SE115s that I really liked too. If I want more neutral I'll just put in the LG quad-beats, they are actually pretty decent, not bass heavy and overall really clear. If you want a portable "on-ear" try Koss Porta-pro they sound great, and they fold up really small for travel.
