How do I get my headphones to work in LH, LX, BA’s weird double-pin sockets in J?

How do I get my headphones to work in LH, LX, BA’s weird double-pin sockets in J?

    Maybe frequent flyers can help me with this problem. I was disappointed on my recent flight LH470 in business class to discover that I could not use my own noise-cancelling headphones in the socket provided in my seat. The seat socket appears to have a nonstandard connector in two parts (see attached photo). One part is 3.5 mm; the other smaller in diameter and shorter. I inserted the 3.5 jack into the 3.5 mm socket and left the other mysterious socket unused.

    I then received sound in only one channel of my stereo headphones, the other was silent – this was of course unacceptable for listening and I had to pass the flight without any access to the audio from the IES as a result. Some users report they get stereo output from using that 3.5 mm socket, but let me repeat, when I have done this, I only got *one-channel output* on two different aircraft whose own earphones have this bizarre audio jack design. My experiences were on an LX 777 and an LH 747-800. There’s nothing unusual about my gear: TripleFi Pro by Ultimate Ears, with a standard 3.5 mm jack.

    I experienced the same difficulties flying business class on board a Swiss airlines Boeing 777 last month. others have complained on line about the BA socket which sounds similar to mine – users report ‘one smaller pin than the other’. I would like to sort this problem out before I fly another 777 aircraft with NZ for 15 long, long hours in a few weeks’ time.

    I carry conversion adapters in my headphones case.
    Rather than buying individual ones, it is better to get a kit that includes most common converters [B][U][URL=’’]like this[/URL][/U][/B]
    I bought one at staples long time ago but they are all over the internet and stores.

    Hi PhatMiles, thanks for replying. I do have a dual-jack adaptor but it has two equal-sized mono jacks of the 3.5 mm standard. I’ve scoured online sources but have not found any dual-jack adaptors that match the specification in the photo of my OP.

    As I see the picture more carefully I realize your agony. [I]Phew[/I]
    I flew LH Biz several times but never had this issue. I researched a bit and could not find a solution. Will look more.
