Ha, the preference list is interesting, I don't know how some stuff works for Apple when connecting the AirPods even with multiple apple ids. I had my girlfriend connect her AirPods to my iPad to watch a movie on the plane. A couple of weeks later I was using airplay to stream a game on the TV, while my gf was in another room wanting to watch something on her phone connected to her apple id. All of the sudden sound goes off on the tv, and after a couple of seconds stream is paused. She comes in that the game was playing on her AirPods. I have no clue how the AirPods connected to my laptop after 1 month of her using her airpods only with her devices.
Yeah, my big gripe is that I keep my computers docked/clamshelled and whenever you lift them, airpods will ALWAYS transfer. So I've had to learn to stop doing that with multiple devices and prevent them from going to sleep.
