qantas noise cancelling headsets

[SilverSleuth]

can someone tell me does Qf supply Noise cancel headsets in their aircraft. If so which ones?. How do u guys find them? Also particularly interested if they are used on the 73NGs? Thanks

Business/First class only. I find them in coat lockers normally. They work good. Don't think the 737NG have them.
