I wouldn't change a thing about these.
I use these mainly for production, switching with DT-770, depending on whether I want make noise around me.
They're super comfy.
I'm wearing them for hours without barely noticing.
Sound is well balanced.
Loving the "telephone" cable.
Every time someone asks for a headphone recommendation I point them to the DT series by Beyerdynamics.
I can't think of any cons.
I guess I've become a kind of beyerdynamic fanboy.
