I record and do my first mix with ATH M50X. Decent isolation, comfortable enough and relatively transparent. Have had to replace the earpads and band pad, but otherwise very solid for me. I could almost certainly do a decent final mix with them, but never do.

I used the AKG Q701 for mixing for years. I mean who doesn't want to mix like Quincy Jones, right? They are very close to the K701s by most accounts. But not perfect. The suspension headband is prone to UV damage, at least in my environment, and I replaced it once but stopped since the headband was almost the same price as new phones. They also have a very delicate solder joint on the power to the drivers, so I learned how to repair that, too. Cool headphones, as you would expect, but too much trouble.
