DC repair at no cost
I had a broken plastic bracket on a DC X11. The headset is 6 years old.
I contacted support; they said no problem - all I had to do was pack it up and they paid for FedEx collection, repaired at no charge, then DC paid for FedEx return ! (So cost me absolutely nothing and came back like new.)
Perfect service !
I suggest you contact Customer Service there (I did this via the website link): Brian Degnan is the Customer Service Manager.
