A friend is flying SQ to the Maldives for his honeymoon soon. He wants to know what type of headphone connector SQ use on the 777 aircraft in Y. Is it a single 3.5mm stereo jack or the dual 3.5mm mono like Qantas use on some aircraft? Or is it something different again. He wants to use his new Shure E500 earphones and wants to make sure he has the right connector. I am sure the folks here will know for sure.
