Airline Headphone Adapter

Here’s an example of a quite strange adapter standard: in airplanes, most of the times a dual-mono TRS output is provided for the inflight entertainment. This means you cannot use your own headphones (unless they’re mono). The airline makes money out of selling these adapters, or – even worse – their branded headphones with two seperate mono plugs on them.
