Putting a mic in your ear doesn’t sound very effective.
I agree. It would be difficult to coordinate everything and would make her look confused. She’ll be such a mess, anyway.
Plus, who wants to listen to her ear?
I think he means we should be saying ‘receiver’.
But I agree with you - I think it’s going to make her look tentative. I’ve seen videos where she seemed to be using something like that, and she was very stilted and constantly pausing in an unnatural way.
