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.

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)

The style, fit, and materials make OTE a difficult and personal choice, even when you know what sound you're shooting for. I've been seeing lots of people online lately complaining about OTE and the hot sweaty ears. I haven't had this problem, but there are many companies selling replacement earpads such as cooling gel. I've gotten a couple pairs of Lambskin leather from Soulwit for Momentum 2 and Momentum 4 and they've been great. I don't get the hot ears with the M4 that people are complaining about and the memory foam is much more dense and high quality than the original thin ones. Both the Momentum 4 and Beyerdynamic DT 900 Pro that I got this year have caused pressure and headaches. They took a couple weeks of use before they were broken in and now I can wear them for 4-8 hours without noticing they are even there.

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.

I still have my momentum 2 over ears and even after years they create heaven when the toddler is reciting Shitespear.... Sennheiser is just a next level company. Word of warning though, they outsource a lot of models so you have to be sure you're buying one that's actually designed and built by Sennheiser, not EPOS. But come on, autistics and research? It's like it comes with a bonus adventure!

Dont wear them to the gym or anytime you might sweat. I bought mine to play drums with and the little bit of sweat fried the circuit board. Sennheiser refused to help. Pretty sad since I love my Momentum 2s. I repaired the M4 only for it to happen again about 3 months later. I tried to repair them again and a ribbon snapped. They are great but theres no reason for the circuit boards to be mounted so low on the ear cups with zero sealant to keep even a little bit of perspiration away.
