Ahh certainly, for music, they blow my X2HRs and K712s out of the water. Well-mastered tracks with a high dynamic range, I can't listen to if not with the HD800S.
Though testing them with Modern Warfare, I was very surprised at how well the HD598s stack up. The difference was more subtle.
I will likely get the HDV820 at some point. I just really hope Sony update the PS5 to support UAC2, so I could at least use it directly.
Currently using the 800s with SXFI dongle, the volume output of which seems to really bug out.
I don't know if the UAC2 support is something that they can update (that would be nice) but I'm using G6 optical out to HDV820 at the moment with my PS5. It works pretty good and the volume knob is usually around 9 o'clock.
