The DT 770s should be just fine, with dekoni leather earpads on them (it's what I use on my Beyerdynamic TYGR 300 R's).
I've heard the AKG K300/500 closed back series are good too as well, I have the open back K712 Pro's, and they have quite the wide soundstage, but are open backs.
As an odd choice, the Audeze Maxwell's are an apparently good set of wireless $300 closed back planar magnetic headphones, that compete with similar priced wired headphones (can be used wired too, but the dongle connected to a pc is quite good). I believe the soundstage is quite good for being a closed back, the USB-C dongle might work on phones too. I tried it, and while personally I wasn't a fan (not deep enough, even with aftermarket pads; granted I have huge ears), I believe that for most it's a fantastic portable headset for PC users/gamers and audiophiles in general for a PC bound device. Lastly, the boom mic audio quality is quite good, and better than my shit webcam mic that I use from 15 years ago.
