Just do a screen grab of his ear/s, and outline where/what you think the earpieces are.
I did a couple of grabs, but they're kind of blurry and show nothing.
The event ended and videos are now up but I don’t know how to do a screen grab. I can give you times when they are most visible:
Right ear: 31:00 and on for a couple of minutes, which include left ear as well.
Left ear: 35:00 for a bit
I compared it with still profile photos and there is definitely something there.
