Here is a headphone that I missed on the original release, but are now being closed out at amazing prices, in the U.S. at least. It's dark, it's bassy, and the details are in the review. I love how comfortable this is, in spite of using the standard earpads. From all I can see, the physical quality is the same as the pricy M100, although the tuning is decidedly different. I ordered from v-moda direct (although it was cheaper on Amazon), so I was able to customize the side earplates.
