Yep for my head X1's need the absolute maximum stretching, my ears are just inside the cups. I don't see any way to bend or strech. Please bear in mind that there is already considerable downforce pressure from the elastic band (yes it's nothing more elegant) at this position. So to be actually comfortable, I'd guess ones ear-to-ear measurement would have to be something like 40 cm at most.
I guess small chinese people designed this.
edit: .. especially considering none of the headphones in my profile had problems with fit.
