I recommend Senns ie800's. You can pick them up for $589AUD online if you look around. They are not over ear but they are the most comfortable iems I have used, have lots of good quality bass, particularly sub bass, really nice vocals, and detailed extended highs (can be a little thin at first but you get used to them). Great for all genres in my experience except complex metal/math rock type stuff - as it's just one dynamic driver. Really good for electronic (I listen to heaps of IDM with them) and vocal stuff.
The ergonomics of the cable is horrible, but fixed with a shirt clip.
I get far more listening enjoyment from my ie800's than from my UM Merlin customs, or my previously owned SM64v2's or Fitear F111's.
