the pads seem to soften up really quick. First few hours they were unbearable, they were stiff almost like they were over stuffed. After about 15 - 20hrs of headtime they softened up and better contoured my head. The rear part of the pad was really rounded at first now they are almost flat. The cavity still seems a bit tight for overear but they dont cause as much discomfort as other cans with this issue.
