Be careful with gasoline around the Bose X headsets.  I have a small motorglider with a fuselage mounted fuel tank.  Distracted while refueling, my Bose X headsets got sprayed with fuel.  The plastic piece on one side holding the earcup literally fell apart into several pieces while the other side hazed over.  While this normally should not be a problem in our Lancairs, it is something to keep in mind given the $170 base repair charge at Bose.
