Earbuds: Connected with phone, but sometimes not as microphone

My earbuds connect to the Fairphone 4 and work as speakers during phone calls, however, they sometimes do not work as microphone during phone calls. I can´t understand why the microphone function sometimes does work during phone calls, sometimes doesn´t.

Thanks for any kind of idea to solve the problem.
