Hd560s vs dt770 pro

Hello there. As title says. Cant decide bettwen these two. Beyer ones needs amp which will come next week, senn ones works good without it. Sound quality is up to each person. With senn ones im slighlty scared of build quality. Hd560s does not scream like im gonna last 10 years, its not looking like some premium plastic. Dt770 pro on the other hand looks its gona last me a deacade if cable survives but since its not detachable its my only concern.

Fell free to provide any additio info to help me ease to decidd which one to keep.
