Hope you were able to find this. This is an adaptor that is very useful for me when I travel. I always keep it in travel bag and with my Focal Spirit One headphones (it came with this adaptor) and with this I am able to experience a higher level of sound fidelity when watching movies inside the plane rather than the dinky headphones that they distribute inside the cabin that must have cost Php150.00 to produce.
Funny but there was this MNL to LAX trip that I took last year and another passenger saw me link up my "in cabin airline system" and he requested for an adaptor from the stewardess so that he can do the same with his Bose headphones. Unfortunately the crew didn't have it however fortunately for him I have two of these in my bag. I gave him the spare and he was a happy camper.
