I acquired these in a trade here in September. They're exceptionally detailed and the bass extends just about to infinity. The tuning is relatively flat and neutral, given that these are catered mostly to a pro audio (and specifically, mixing/mastering) crowd, and as such, you'll hear absolutely every tidbit the song has to offer. Being planars, they respond decently well to EQ, though I didn't play too much with this beyond a cursory check with a prior dongle DAC.

This model has the metal pin for holding the headband onto the cups, though the cups themselves appear to still have some plastic components. I believe this means they're the more durable "silent revision", but I'm not 100% certain. No indications of wear or impending breakage, for sure. The left pad is a bit of a pain: the velcro/hook-and-loop seems to be wearing out, and the pad falls off if the cans are placed on a table laterally like shown in the picture. Stays on just fine when actually on your head or on a headphone stand.

Asking price includes shipping and G&S fees. Cash offers preferred, but will consider trades involving Tea2, U4S, or Monarch II/III.
