Not sure what kind of aircraft you're flying, but most I'm aware of have the two-plug configuration. David Clarke was the gold standard for a long time with the small plane, propeller crowd. If you're wheeling a B727 around, the Bose Aviation X or Sennheiser will work. All those are two-plug headsets.
