Hi,
I just commented on another thread, here i'll just copy and paste what i wrote:
I think the
crossroad mylar x3s (or xbs) are a good bet. They cost $57 for the X3s and $65 for the XBs (w/free shipping from jaben.net). I purchased mine about 2-3weeks back and i'm very happy and think they're well worth the money.
Here for more info:

(Xb version means more bass)
I was using the standard ipod earphones and couldn't believe how long it took me to realise how bad they were. These earphones really excel for me with dance music. The boom in hard trance, or hearing the drums in drum n bass, really impressed me, and also hearing the low notes on music with piano
But don't take my word on it, read around you'll see a lot of people recommending this brand!
