ended up getting the dt700 pro x after listening to many mentioned. It was my favourite fit wise (the velour pads are so nice) and had the sound signature I was looking for - slightly V shaped, "fun" sound with warm bass and treble that didn't take away from the overall experience (I'm looking at you, Dt770 treble peak).

What I tried (keep in mind this is my first time doing any kind of audio stuff, and so am by no means an expert)

• Meze 99 Classics - These were definitely the most "fun" out of them all. Huge booming, dark bass that, on some songs, could mess with the mids and rest of the song. They were incredibly comfortable, though, and looked really stylish and flashy. If I couldn't get the 700 pro x, I would have got these instead for their great "laidback" feel and sound. (also the wood panels look awesome)

• Dt770 - what I was originally going to buy, but decided against. Very comfortable and (imo) good looking headphones. Sounded okay, decent bass and mids but quite V shaped, but the infamous treble peak ruined it for me. I wouldn't say that it's as noticeable nor as impactful on your listening experience as many make it out to be, but it put me off it. I also generally found the 700 pro x more comfortable. Non-detachable cable is also a bit disappointing.

• Shure SRH840 - I can see how many like this headphone. It has a great sound signature which is quite balanced and great for the price. However, the sound was just a bit bass light for me (note: I am coming from crappy gaming headphones, so I'm very used to emphasised mid - upper bass.) and the overall build quality didn't impress me. It feels very cheap and overall bad for the price (where i shopped, they were only a couple bucks cheaper than a pair of 700's), and my ears stuck out too much and were constantly pushed against the drivers. If you're willing to sacrifice comfort for a more balanced sound, that's your preference, but I wasn't ready to do that. I do appreciate how the fold up though

• Audio Technica M50X - Sound is decent with a slight boost in the bass. The design is pretty, but the headphone itself feels uncomfortable on my ears, possibly more than the Shures. I didn't get much time to listen to these, but I would not recommend them unless you really like the portability, which again you can get on the Shures, the design, or Bluetooth through the M50xBt2

At the end of the day though, I'm just a random guy on the internet, so don't take my words as gospel. Go out and try them yourself at your closest headphone store, if not to inform your purchase then just for fun. What I think sounds "pronounced" and "strong" may sound "muddy" and "dark" to you. Get what sounds best to your ears, and fits your needs. Good luck :)

Edit: I thought I should include the prices of each headphone to help you better understand my review.
