Comfort is a very important thing. But I think at first they must improve these two points.For the left they should replace it with metal and for the right they should add some kind of a screw instead of that rivet. Because today if something breaks down I must replace the whole headband and it costs 144 €!
And by the way when are beyerdynamic going to make headphones with detachable cables?Maybe they don't know but it's very useful especially for portable headphones.
