Beyerdynamic DT770 vs Sony WH-1000XM4

I was looking for something that was comfortable with no sound leakage that I could drive directly from a laptop and not need an amp. The main purpose was just to listen to speaking videos with the above requirements. However, after reading the reviews it sounded like they would be good for music as well with an amp - which I do have (Mojo). So, unless I was wanting to listen to true audiophile music, I thought maybe this would save me from having to switch back and forth between headphones when I took a break from speaking videos to listen to some music At least that Is what I had hoped

So my first pair of headphone I got were the beats wireless studio, I recently decided it’s time for an upgrade and I had bough the Sony WH-1000XM4 and I love the wireless and battery life about it. I also like the noise canceling but once I started listening to it more I could tell they sounded ok but I wanted better sound. What are the best sound quality headphones for under 400$?

Isolation - They have a lot of passive isolation to them when you have them on (can't hear anything with music on). Outside of the headphones they don't leak a lot of sound (unless you have them cranked, and even then it's not blaring). If you want to use a mic while listening to music, you wont hear yourself at all. Cons: ***Cable length - You will need twist ties to use these as portables, the cable is extremely long Cups don't rotate in both axis, so carrying these around gets tricky (awkward shaped and big)

And the ANC (active noise cancelling) was AMAZING. I could be sitting right next to a whole house fan and not hear it. I was blown away. RANGE: Twice during the day I tried walking around while on a call

I'm not concerned with the way they look. They aren't displeasing to me - but I'm also not thinking these are the coolest looking phones, but I don't care about that.

Comfort: I wear these for hours straight and haven't found them uncomfortable or heavy. Software Support: Not terrible but not great. For some reason, the "Headphone Connect" app (which is used to more finely control and configure these headphones) is only available on your phone; there is no desktop version. Within the app you can change the equalization profile, change what the general purpose button does (Google Assistant or Noise Cancellation mode), and update the firmware (UI for doing this isn't straightforward and buggy)

They are a bit muted in the sound signature which can make them less fatiguing than other, more analytical, headphones. Mids - A bit to high level for me, it tended to make punk rock music sound very close and muddied Lows - A bit boomy but very spacious Audio Technica ATH M-50x Highs - Quite good representation, a bit cold though Mids - Nothing special, no major issues though Lows - Too over-emphasized -----------------Comfort--------------- Beyerdynamic DT 770 - Winner Perfect. I wore these on multiple occasions for more than 7 hours and never noticed any pressure points or discomfort. The headband is larger than average to distribute the pressure

These are by far some of the most comfortable headphones I've ever used. The noise canceling is top notch in every environment I've needed to use them (mostly the office with an open concept, and airplane travel), which means I can listen to music or other content at a reasonable volume with full clarity. Having them paired to my computer and phone at the same time is a great convenience that will be a requirement when I replace them eventually. I use them for ~8+ hours a day, Monday - Friday, with minimal ear fatigue
