What do you call a microphone that is held beside the face?

I don't know a term denoting a microphone usually held on speaker's side of the face. See following image that shows in white:

I googled images pertaining to the types of microphone, but that did not help. It shown me following results, that does not include the thing, of which I want the term.

After encountering such types, I had a doubt, whether the term which I want to know is just "microphone" or not.

Sample sentence can be:

I saw Sandeep Maheshwari giving a comprehensive lecture in front of a large audience via a device held on his face, called a _____ ?

Solution 1:

It is a "(flex) mic boom." The tip can be referred to as a "microphone." Though a headset boom is much smaller than a traditional microphone boom, it's still called a boom for some reason.

I am also seeing "wireless headset microphone" as a better description.

The "boom" term seems to be more for wired headsets.
