I'm definitely down to these two. To anyone who has heard both, can you compare? The sense I get is ATH sounds "better/more balanced"...but that it's a little less on the low-end.

I want bass to be present (gym use, iPod, all kinds of music), but don't want it to boom. I had a pair of V-Moda Bass Freqs and HATED them. Too much muddy boom.I find myself wanting to go with the Audio Technicas, but just fear that I'll be wanting a little bit more low end.

I used a pair of Vibes in the gym until they broke, to give you an idea of the sound I'm coming from. At work I use the UM1s and really really like their sound. That is plenty of bass for me, and the mids and highs feel warm and not shrill.

I seriously waffle between the two constantly - an issue I'm sure you guys are quite familiar with.
