Phone not recognizing a particular set of earphones.

[AC Question]

My Moto G3 all of a sudden stopped recognising my earphones. The earphones are working fine when connected to other devices and other earphones are working when connected to my mobile. Can someone help me with this?

The earphones may not be connected properly. When I encountered this situation, I usually slightly turn the headphones。 You can try several directions.
