Left earbud not giving off any sound

#1

My left earbud won’t let off any sound, does anyone know why this is?? Is there anything I can do to fix this?

#2

Try to reset the device,

Try to make sure that it is clean on the pins in case if it was not charging (as you did not state if it was or not)

If not contact the soundcore service department and ask about that and and depending on their response and how long ago it was bought, you may be able to use the warranty.
