Unsurprisingly the BoboVR M3 Pro headstrap is very comfortable compared to the default. I can't wait for the the accessory facial interfaces to come out and the whole setup will be really nice.
i'll probable look for a cushioned centre/headpad to go from the front to back.
Can't wait for mine to be shipped. Have you tried it without the facial interface? Some people are doing that for a slightly wider fov I think, although I believe the tradeoff is more light leak.
