I'm looking for opinions on good mixing headphones. I've been using Sony MDR 7506 for a couple of years and they are starting to peel, so I'd like to reserve them for recording situations and upgrade to something new for mixing.

If I'm understanding correctly, open back are superior for stereo image and bass so I'm interested in those. Feeling a bit of choice paralysis since there are so many options / different models that people swear by.

Also wondering how loud are they for those around you? Would being in a midly treated room with the door closed be silent from outside the room?

I'll be saving up for whatever I decide on, so budget isn't a big issue, I'll wait longer if needed. Hoping to stay under $500 Canadian or so.

BTW I would put "true" /flat sound as a priority. Also I have small ears.
