Many BT earphones for Android have in fact mikes, because they are 
intended to be used with the phone, meaning having a phone conversation 
is a certain possibility.

Has bitten me more than once because they can make a phone call tapping 
the single button in a certain manner. And it phoned the first entry in 
the address book, which was some one not pleased at me phoning her by 
mistake (I had her business phone number written for calls she made to 
me, but she made the mistake of using her personal phone during the 
pandemic, being forced to work at home. She could not understand how a 
stranger had her personal number).

I would like to have BT earphones with no mikes and no phone call making 
capability!
