[IBeN8]

By portable I mean an over-ear with good isolation, very comfortable, and a manageable cord.
 
As far as Sound goes I'm looking for a relatively balanced sound with a slight emphasis on Mids and Bass.
 
I own the v-moda M-100 and i like it a lot, but am looking for something else primarily because they are just not comfortable for me(pads too shallow). I could also use slightly better Mids.
 
Suggestions?

Sennheiser Momentum althought depending on your ear size the pads may be a bit shallow.  I found them quite comfortable, but the bass was a tad colored for my tastes.
