No, I don't know that. But I am sure Kiwi Flyer will be able to enlighten us.

I carry an adapter for the QF two-prong connections and the adapter fits inside my Shure zip case with the earphones. I have not had any problems on any OneWorld flights with using the E3s with either their 3.5mm jack or the QF-style 2-prong adapter.

thanks Kiwi Flyer
As I'm buying the Shure E3 which are sound isolating and not the noise cancelling type headphones - Would it matter if the seats in economy didn't have the noise cancelling circuitary. ??

Also, if business class seats audio is a 3 jack type prong, would you presume that economny is also 3 jack (but probably without the noise cancelling circuits)

From memory the non-refit a/c (ie A320, 737, 767) all have 2 prong fittings in all classes. I presume a 2 prong plug headset in a 3 prong plug? IIRC the headsets are the same on all a/c in economy.

Sorry Kiwiflyer , but what does IIRC stand for ??

Also, are you saying that a 2 plug jack that I purcase at D**k Smiths will fit into the 3 plug fittings in the economy seat ?? So sorry for the questions but I'm a bit confused with plugs/fittings/jacks etc.

IIRC, the two prong plugs will fit in the corresponding audio locations of 3-prong sockets. i.e. Same individual plug dimensions and separation.

thanks Serfty.
Still don't know what IIRC stands for (& it's not my name)

When using a 3-prong socket, the two audio connections are the same spacing as the QF 2-prong adaptor and provide left/right audio. The third prong is either to provide power for the headphone's active noise cancelling circuitry, or to provide the microphone feedback for the active noise cancelling circuitry built into the seat.

Either way you can use the IFE system with any standard head/earphones using the 2-prong adaptor and ignore the third socket.
