How to refer to one side of headphones? The word "headphones" is in only plural form, referring to two main components (speakers?) that are put in two ears.
Now my question is how to refer to each side of the headphones separately? (It is relevant for example in case that one of the sides doesn't work anymore.)
I know that I can say simply and generally "one side" doesn't work, but in my native language I can say "headphone" in singular form, then I'm looking for the accurate term for each one of them as a singular)
In addition, there is "headphones" that come/s just for one side only (see second picture), normally for people / host in TV shows, or security-men / policemen.
