I lost a pair of airpods (swiped out of my office at midnight! wtf!?) and to this day I casually open the find my app to check on them, and they bounced around locally for a few days before making their way to somewhere in Turkey. They still seem active, despite being in lost mode (they shouldn't work in lost mode unless there's a known exploit?). Also, I've tried dozens of times to get my own airpods to play a sound from the find my app, just to see what it sounds like and have never gotten any sound to actually play. I am not sure what I am doing wrong.
