Are airplane headphones 3.5 mm?

It is pretty much the universal standard for audio, works on phones, planes, car radios, etc. The only adapter you might consider having is the dual pin adapter, often sold as the airplane adapter. Some airline systems use the two pin system, some the one pin system.
