DT-770 Pro 250 Ohm : I have never had a more uncomfortable pair of headphones

I watched and read many reviews on the DT-770 Pro headphones before purchasing, one thing that was repeated in all of the reviews was the level of comfort, but after just two days of use, I am considering returning them, honestly it isn't uncomfortable, it is downright painful to wear these headphones for more than 20 minutes, even when I wear a thick soft hat under them, it still doesn't stop the pain of them slowly digging into my skull. I have personally used a vast array of headphones, from cheap to expensive, gaming to other studio headphones, and never have I had this kind of experience, very disheartend in all honesty, as I love the sound and really enjoy how much background noise they shut out, but if I can't handle wearing them for more than 20 minutes at a time when I need to wear them for hours to work then they're useless to me unfortunately.
