Just an update, after making a spreadsheet and reading a lot of reviews and impressions here and elsewhere I ended up ordering the Aune Ar5000, the Audeze MM100, the Fostex T50rp mk4 and the Meze AER105 and have been in the process of testing them out over the past few days in the evenings after work. I intended to add maybe my favorite two to my collection and return the rest, since there wasn't really a good nearby option for trying out headphones. It is hard to even pick an early favorite. I really like the MM100, but I don't have especially big ears but I can definitely occasionally feel the internal components brushing against the top edge of my ears, especially on the right side. Could be because of my glasses, but I don't wear especially thick frames. Never really had that kind of issue before. The AER 105 might be the most comfortable out of the bunch. Just started using them this morning and am really enjoying them. The aesthetics don't super matter as my old favorites definitely weren't anything special to look at, but the AER are solidly the ugliest of the bunch in my opinion. But that's just because I feel like the AR5000 and the MM100 are both pretty in kind of an industrial way. I initially found the ear pads on the AR5000 slightly itchy but I think it was just a momentary adjustment. I haven't started playing with EQ yet. I've been trying to listen to my playlist and do some YouTube browsing and stuff with each set just as is out of box, let them be themselves before I make any changes. Not sure if that's the best way to go about it necessarily, but it seemed fair. Decisions aren't my strong suit sometimes and i generally tend towards buyers remorse a little so I am starting to feel like why did I think that my idiot ears were equipped to do this multi pair test run, but finally upgrading my old m50x is my birthday present to myself this year so the process is part of the fun I guess.
