Momentum 2.0 Over-Ear (M2 AEi)

I don't think I've tried those particular Audio Technica ones, sorry. The one big issue I came across using headphones with Quad Cortex is to make sure you use a TRS (3-ring) jack and not a TRRS (4-ring). I tried my old Sennheiser Momentum 2.0s which have a 3.5mm 4-ring jack using an 3.5mm to 1/4" 3-ring adapter and they just screwed up the sound entirely. You might get lucky with some other make, but I'd just play safe and get headphones with a native 3-ring TRS-jack. I think the M50x has that 3-ring jack, so you should be good to go with those.

I have momentum 2.0s right now and the button controls work well for me. I’m looking at the Bose QC (not ultra) right now even though I’d be willing to spend much more just to have touch controls. I tried the Apple headphones but the weight and band got to me unfortunately.

What's your experience/estimate on durability of each Sony 4 and 6? I went with Bose and wasn't very impressed with build quality compared to my old Sennheiser Momentum 2.

I really like my Sennheiser Momentum 2. I have nothing to compare them to apart from my open back HD595 (which are better but leak a lot of sound)

Looking for the best ones possible. Budget is $2000 and I’m ordering online. I’m focused on accuracy and appreciate a wide sound stage. They’ll be used at home or on walks. I’ve had the sennheiser momentum m2s which had great sounding bass but was bloated, have the Px8s and find the bass muddy but appreciate the separation of instruments. I also prefer them to have a clean minimal look but am open to something like the focal bathys mg if they sound better. Currently looking at the Bathys mg, the Dali IO-12, Dali IO-8 or the bang and olufsen H100. Noise cancelling performance isn’t important to me.

As was stated below, Bluetooth is a fickle beast as not all are created equal, both in source and receiver. I have a few Bluetooth headphones, one being an old pair of Momentum 2's, and they are awesome for music and the like, but if I'm playing a game with them, the de-sync alone is highly jarring. I have a much more modern set, and they have Bluetooth 6.0, and when used with a device that I know has a Bluetooth connection that is actually really good, they work perfectly with no (perceivable) lag or audio issues. That being said, I don't really have massively high standards, so long as the sound is clear, not muddy and can put out a good volume, I don't really mind.

Thank you! I would also lean towards sound over comfort, as long as it's not too uncomfortable with long term use. I have a nice pair of headphones (Sennheiser HD1) that I have been using for mixing and whatnot but they have no noise isolation, and it would be nice to be able to just use one pair of headphones for everything in my little home studio. Just out of curiosity, how long have you been using the MDR7506 and how have they held up to wear?
