How do you find the clamping pressure to be with extended listening? And how well do you feel like the clamping pressure could be reduced in case someone found them too tight?
I've had several closed headphones, like the Sennheiser 280, 380, Momentum, Beyerdynamic DT 770, DT-150, Denon AH-D5000, Kef M500 and B&W P5. The clamping and long term wearing comfort is among the best I've encountered with closed headphones. The pads don't touch your ears, so the ears don't become sore like with on-ear headphones, and the clamping pressure is no problem over long periods. The clamping is firm enough to guarantee that they seal properly, but not like the studio style headphones like the Sennheiser 280 which can seem like they put your head in a vice. I don't know what the headband is made of, but if it's metal (which it feels like) then you might be able to bend it to relieve pressure.
