My friend and I both were on a flight but not seated together. Instead of just sending a note through AirDrop back and forth, I had this weird idea… we both have AirPods, so we traded just one each, both turned on Live Listen, and had a little chat! We only tried it to see if it worked. Wasn’t trying to be those guys who talked the whole flight.

This is a pretty interesting idea. Not practical, perhaps, but a fascinating proof-of-concept.

For folks unfamiliar with Live Listen, here’s Apple’s official support document that explains how it works.
