beyerdynamic DT 700 PRO X

At first, I tried 770 pro x. Same drivers, different tuning and housing.

After 4 days of testing, for me- the treble was too harsh and after trying to play with eq, paper mod and audio interface I still couldn't listen to them for more than 1 hour. Just didn't suit me, but overall comfort was great and better than 700 pro x, that's the only minus for me, for now.
Sound, more premium feeling, design, earpads and second cable- all of these are big pro's for 700.
Overall- really enjoying these. EQ'd them for my taste, added some lows and got a feeling- that is exactly what I was looking for.
If you are sensible to treble and deciding between the two- get these asap.

Thankfully, Thomann provided me an excellent service and quick return of 770 and new shipment of 700. Amazing work.

tldr: Pretty good headset for what it is and a price tag, clamping force on my head will get looser and then they will be 10/10

So my previous headphone experience is using a set of Pioneer SE-MHR5s for casual listening, and an old set of Sennheiser HD 380 Pros for Mixing. I was very excited to get a new pair of headphones for mixing music, as well as practical use such as voice calls and games.

Sound: This is why I ended up returning the headphones, the high end just sounded harsher than anything I'd experienced before, giving me ear fatigue after only a few minutes of listening. After applying some neutralising EQ I found music more listenable, and almost decided to keep them, but Discord Calls and Games I ended up finding equally unenjoyable, to the point of switching back to my old headphones for those activities. I want to point out that there is a great deal of clarity with these headphones, everything is nicely separated and generally I can tell that the sound quality is very good, but these headphones actively pained me to use so I can't excuse them.

Comfort: I really can't knock the comfort, I'm almost sad to see them go, they're incredibly comfortable and I wore them for a whole day with no ear irritation.

Quality: Solidly built, however they're a little inflexibile which is irritating, great for removable parts though, should become an industry standard practice!

Side Note: As these are quite new headphones, you will have a hard time finding good profiles for EqualizerAPO or Peace EQ, they haven't been made yet it seems.

Overall: Honestly I'm disappointed I have to send these back, they're very comfortable and good quality, but the harshness of the high end and the general heavy-handedness of the bass left me feeling fatigued and depressed about even listening to music, maybe you'll have a better time with them if you're used to high end sound but both of my previous headphones were more bass-oriented and the transition was too much! I'm thinking about making my next pair a set of Audio-Technica M50Xs, as I've heard the bass on those is great and the highs are more muted, which suits me just fine.
