Aukey EP-T21right earbud has stopped working, what do i do?

These headphones were given to me as a gift and were working fine for the past few months, I woke up yesterday and realised that the right earbud has just stopped working. There is no light showing on it and i dont understand- I did not break it and theres nothing obstructing it from charging.
Im upset and confused.

Hi @sonoshudde,

Thanks for joining the Community. Have you tried to reset the earbuds following the instruction on the user’s manual?
