I know a number of friends who have had nothing but problems with the new DC headsets (noise cancelling carbon fibre ones) but they may have fixed that by now. If you ship with UPS they can charge you a processing fee of a few hundred dollars and basically have you by the balls because you either have to pay it or go through a long process of paperwork bringing the item through customs. (happened to me)
Like everyone says use USPS or Fed-Ex NEVER use UPS. Good luck.
