I have a bit of a big head too, at first clamping force did feel tighter but it’s perfect now it’s worn in. The ear cups are nice and deep and very plush so I no longer have my big ears rub on the driver like the 990s and seinheisers do to me

Dt900 pro x, I see a lot of comments for 990s 770s 880s etc. the 900s are in much more comfortable

I’ve got the xm4s and they’re just bad. Compared to something modest like some dt770s they sound awful so I just don’t enjoy listening. I appreciate they have anc though but not worth it for the poor sound quality
