What's your source? If you use an Android, there are a few nice EQs with bass boosts that can turn my bass-neutral HM5s into Beats clones if the song calls for it (link). iPhones, to my knowledge, have a bass boost built in. On PC, Winamp (and several other players) accept VST plugins, so you can use a bass boost there too.
Software bass boosts can turn any headphone into InstaBeats. I'd recommend getting the headphone that best fills your non-bass related needs (bass-anemic cans won't do good, but anything neutral or above), and then just cranking up the bass boost to your liking.
