I've had ATH m50s and loved them, but did not enjoy wearing them.
I've had the Vmoda M80s and they were great, but to my ears there was a bit of distortion in certain blues-ey types of music in the mid bass range.
I tried a pair of Sony 7506s and, to my ears, they sounded better than either of the others, in a clinically sharp kind of way.
But I keep going back to my Etymotic MC5s. I dont find them to be lacking in bass at all.
Im looking for a set of open or closed headphones that I can use at home to listen to a very wide range of music ranging from classical, to hip hop to the black keys and white stripes. I use a Fii0 e6 on a 4th g Nano.
Ive been looking closely at the Allessandro Ms1i's or some Grados in the sub $150 range for home use, and Ety HF5s for portables.
