Good in ear headphones?

i have grown to like my sony mdr xb40ex, they got the boom, hehe.

can clearly hear the lowend in many mixes that is nice surprise after bad experiences with earphones.
 
I've a pair of CX300s and I'm not particularly gone on them, I had cx200's before these and I much prefered them. I would say watch out for the tons of fakes on ebay though
