Without pressure 2cm deep. The inner clearance is about 4cm wide and is cut diagonally at the bottom with a short side edge length of 5cm (back) and the long one of 6cm (front). Might be too small overall for very large ears. However, the pad is very comfortable on the skin and nice and soft. The pressure on the ears is low. I wear glasses and have zero problems with the earpieces. Very good audio quality. I have already been told that I can now hear much better. Maybe that makes up for it.
