I have both and agree with you about the confort but for me there is a big difference in sound quality, the mic also makes a huge difference between those two when using them for video calls. I'm quite happy with the AirPods max, still wish they had ubc-c though.I have twice tried to fall in love with them but ultimately found them less comfortable than my Sony XM3s with no discernible difference in sound quality. The biggest downside of the Sony’s is lack of multipoint, which I guess the XM4s added. But the Sony’s also pack up so compactly. So despite my fandom for all things Apple, I just could not justify them.
The thing I hate is battery life, feel they lose a lot of juice even when not in use and that means in some occasions when I want to use them, the battery level is low even when I haven't use them for days.
