    Could some one let me know if I am on the right track with this. From
    what I can tell those double jack headphones you get on a lot of
    aricraft these days has a jack for the right and left headphones
    respectively correct?? If this is the case it would be quite easy to
    jus connect these together on a single stereo jack correct?? Or is
    there a problem with the two "grounds" on the sperate jacks?? Would be
    great if someone could let me know if i am right or i am in some dream

    AFAIK you're correct. The reason it's non-standard is to make you buy
    headphones on the plane. Isn't capitalism brilliant?

  3. The way it's always been for me is that the headphones are free, the double
    plug is to stop you from stealing them when you leave (cause they become
    Also, each one of the double jacks works fine as a stereo jack if you plug
    in regular headphones, so no need to use the crappy airplane ones.

    And yes you could rewire airplane headphones to use a stereo plug or use an
    adapter but it's REALLY not worth it. All you need is to connect the grounds
    together, and then connect the ring and tip.

    maybe one jack is for (mono wired) headphones & the other is for
    microphone; if so, you can not wire them together
    (well you can, if on the other side on pannel is the male jack also
    wired (stereo?) - one plug for phones out, the other for mic.)

    the double plug is to stop you from stealing them when you leave
    I think Tim is correct.

    Last time I flew they said "Keep them".

    Years ago, when they rented them for $2 and were saying,
    "Don't use your own headset; it might screw up our system",
    I made my own adapter and used my Walkman phones.
