Thank you @hanselmann
!
along with my profile name, you'll be surprised with the fact that I have 10 or so sets of beyerdynamic headphones![]()
That's about my level as well

Hello, they are not the same. For T 90 and T 70 it's a one-block design with click mechanism. For DT 1770 Pro it's a design with two brackets, that are screwed together from tzhe inside.
We thought for a professional headphone, it would be more important to have it user servicesable with visible screwes than having seamless surfaces.
Very welcome...
