I'm actually shopping a pair of closed headphones to - I guess I'd say - replace, my HD6xx. They're fantastic, I'm just in a situation where I: 1) Don't need any isolation and can use my desktop speakers, or, 2) want total isolation.
I'm running a Modi 3 DAC to a Vali 2 amp (with a EH6922 tube), DAC fed optically from a MBP, or the amp directly from an NEC P650 CD player. I'm using the preamp out of the Vali 2 to my speakers - terrific setup.
Anyway, semi-recently I had ATH-M50s, very solid, but lost in SF ... used Senn 558 for a bit, switched to a pair of DT-880s, then to my current HD6xx.
I've been considering the Custom Studio 80 Ohm, seems like a better option vs. the DT-700 (even if just for the detachable cable without having to mod ...) but have also been very interested in the X Meze 99 Noir.
Comfort almost supersedes any other attribute - I mostly listen to alt/alt-rock.rock, electronic/trip-hop, some classic rock, some folk/acoustic. I thought the DT-700s were a touch too bright (they were pre-Vali), love the balance of the 6xx.
Suggestions in the $200-ish range?
