So the headband on both sides of my xm3's has cracked, which can and has resulted in the headband coming away from the body, and exposing the wires, very easy to break, not good!  The very thin plastic has cracked in normal use, I am by no means heavy handed with them.  It looks to be a design flaw in this area.  Why Sony uses such thin and weak plastic in this area?

Sony also refuse to look at this matter as it doesn't fall under warranty as it's "cosmetic damage"!?  No way.

This is not what I expect from a £300 pair of high end headphones.

Should have stuck to Bose.
