Sennheiser - 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.

I have the momentum 4 over ear. Was bit disappointed in the plastic as I replaced my momentum 2 after 6 years daily use (battery) which had metal and leather and looked better than brand new as they retired (gave to a colleague who could replace batteries). I've had the 4's for about 2 years now and they are great. For gym and running etc I do prefer in-ears. So far Sennheiser to me are well built and sound great. I've had mine in light rain a couple of times without issues but I'd still avoid it (I often have a hoodie to cover if needed). I do however always have my in-ears with too as it is sometimes more convenient, especially when active. You could look up which headphones are easy to replace batteries and go from that. I've had success repairing other headset (mechanical breakdown) using a 3d printer and soldering skills, albeit time consuming).

1. ZMF Vèrite Closed. Wonderful noise isolation, widest soundstage I've ever experienced on headphones (more than even HD800S and Atrium Open, though admittedly still very little compared to speakers). Nicely forward vocals with decent timbre (huge for CBs), deep low-end and a good amount of high-end clarity. I really liked the Auteur solid hybrid earpads on these. My pair had stabilized wood, and were therefore too heavy for me, so I got rid of them relucantly, despite VC being my favorite sounding CBs ever. I like the comfort on ZMFs when the weight is closer to 500g however. 2. ZMF Atrium Closed. A very different presentation to the VC, isolated a lot less noise, has the best low-end I've ever heard from headphones (great quality, and just about the limit for how emphasized the mid-bass should ever be), less forward male and female vocals than the VC but still adequate. A bit less detailed low-end. I haven't experimented enough with earpads, thus far stock sounds better than Auteur Solid Hybrid , but isolates even less outside noise than those, I need to try some suede options as I'vd heard they bring up the vocals further. 3. Capra Audio Ouroboros. These have insane noise isolation, better than the passive isolation on any other headphone, including ANC ones. Too strong low-end for my tastes but still quite good vocals and treble. But a drawback is that they isolate noise so much that I experience discomfort from the cabin pressure sensation they give me. If you need to quieten outside noise, these are great for the budget you can make then at. 4. Focal Azurys. I only had these for a week, but my impressions were mostly positive. Take my audio impressions with a grain of salt from here on since I will be detailing headphones from memory. I found their sound to be good for a CB, slightly wonky upper mids (possibly because of the early ear-gaim elevation), but great highs and a punchy low-end. Comfort sucks without a capra strap, but great with them, ans very comfortable earpads. Questionable longevity given Focal's hinge problems with the new design (at least the headband doesn't snap in half). 5. Denon D7200. Needs some EQ to tame the treble, otherwise very good for a fun tuning, lovely low-end, decently forward female vocals. A bit too unnatural timbre for my tastes. 6. Denon D5200. 7200 with a more muffled sound, arguably better stock tuning but too much low-end and not enough high-end. Drivers seem worse and therefore EQ's poorer than 7200. 7. Focal Elegia. Trainwreck stock, but a great EQ platform. Focals old drivers have great dynamics and with heavy EQ you can get these to sound wonderful (so long as you don't like too much bass, since those drivers distort somewhat fast in the low end). Poor build quality as with all last-gen Focal headphones. Honorable mention: Sennheiser Momentum 2. I recall liking them when I got them, but tastes have changed significantly since then. I honestly don't know if I'd find them awful or not now, but they get an honorable mention as being my first pair of non-gaming closed backs. ANC speedround (I ultimately dislike all the ANC headphones I've owned, be it comfort, poor ANC or abyssmal sound). PX7 S3>XM6>Bathys>QCUltra>XM3>QC45>XM4>XM5. PX7 S3 wins in comfort paired with sound (with some EQ) but poor ANC compared to Sony & Bose. XM6 dominates in ANC and EQ's well but has poor comfort for me. Bathys has great sound, crap ANC (waste of money as travel headphones). QCU has great ANC, pretty good sound with EQ but annoyingly high ANC noise floor with no means to turn ANC/pass-through completely off. The rest are completely irrelevant. Sorry for the crap formating! I don't know why Reddit's mobile app is so bad for text formating.

And why? I have been using Momentum in and over ear headphones for years and am very satisfied. Especially True Wireless 4, the sound quality is insanely good.
