Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
I have the ATH M40x which are a lot better for bass heavy material and mixing then the M50 (check Oratory1990 here on reddit for analysis and eq), and the DT990, both are good but it is really tricky to properly mix on headphones at all. I'd go DT990, oratory1990 eq and cross check on as many speakers as possible. You'll be good.
Decided to do the same thing with headphones and micro. Stopped between dt770 pro and ath m50x. Went to the store to listen to both of them before deciding to buy anything at all aaand i liked m50x more - they have more "consumer-ish" sound imo: better bass, better highs, almost the same mid as 770 and there was limited color version that i really liked. While on the other side i felt like 770 are more suited for creating music, not listening to it - they show all the flaws in quality any track has.. https://preview.redd.it/ej8jb4j4snzf1.jpeg?width=4096&format=pjpg&auto=webp&s=518f65faf3c2f4903536eff1219da084c6b3a81e
If you have studio monitors? Tbh…. I prefer my ATH-m50x over my 660s & dt770. Dt770 also had the misfortune of worsening tinnitus from the harsh high end.
I mostly use Beyerdynamic DT 700 PRO X. I opted for them because they have a fairly neutral sound signature which is good for monitoring. Additionally, they are closed-back so they better isolate against room sound. My biggest complaint is I'm not a big fan of the position of the cable connector into the headphones. It's mini-XLR which is great, but the connector itself sticks out quite a bit. You might find it pokes into your shoulder or gets snagged on your clothes if you move your head around. It's a minor thing, but definitely something I wish was different. Other than that, I'm very happy with them and I do recommend them. They're a bit expensive, so if you're looking for cheaper options, I would consider the Audio-Technica ATH-M50X or Sony MDR-7506 which are very good, tried and true monitoring headphones.
I have them, among a lot of other options. They have a purpose. Great for the artist when vocal tracking. They’re my go-to for that. But I’d never mix on them.
Do not agree about the Audio-Technica's I actually don't understand why so many people like the M50X specifically.
