They do not charge for headsets in INTL Coach. As a Gold or Plat they do send a few coupons for drinks or headsets. Note I said a few.
As to using your own headphones, they will not allow it, but then again I have watched people just wait until after the FA's go by, then pull theirs out. Don't ask, don't tell is that deal.
