All I can think of that it’s some sort of Bluetooth device. The projection might be an antenna. Two projections? Never seen one so I’ve No clue here.
I'm thinking antenna, too. I should ask next time I see the setup, but it might seem pretty intrusive if it isn't really an antenna. They point downwards, by the way, almost to the jaw line.

@Ragman,
Ragman-
Thank you.
I take it they are transmitting sound from a source (e.g., a Smartphone on the person) to the person's ear.

@gollum,
They are likely wireless earbuds, probably Apple Airpods. The part sticking down has the microphone for hands free calling and often touch controls.
