In cabin medical audio jacks [2] are the likely explanation, but it would be easy to inspect those: https://i.stack.imgur.com/5w241.jpg https://i.stack.imgur.com/5w241.jpg * Unless someone had made dongle that once inserted looked like the same plugs, but raised enough to hide the dongle and match the color/texture of the surrounding plastic. The fake plugs on the outside would not even need to be functional and the device could be set to start on a delay, so whoever is placing them is not physically on the flight when it starts. It could even have an accelerometer to turn on after take-off and turn off on landing. If the person intentionally booked a seat at end of the plane, very likely they could easily add it when everyone is trying to leave the plane.

This must be the explanation. The one thing I can't quite understand though is how someone could be simultaneously so very technically clever and yet execute such a mundane level of prank. This could be so much more epic if someone got more creative with the choice of audio track. I mean, it could be anywhere from totally hilarious to actual terrorism. Scary to think of the possibilities.

  If this is truly the explanation though, I wonder if the public will ever get to hear confirmation or if they'll just remove it and refuse to talk about it / threaten employees to keep it quiet.
