Warranty on Earbuds

Just for clarification, by "earbuds" are you referring to Apple AirPods, EarPods, or Beats Earbuds?

Regardless, Apple provides a one-year hardware warranty against manufacturing defects on most of their products. If you feel that this could be the reason, you will need to have an Apple technician examine your EarBuds to verify your findings ... and, if they concur, they you may be able to get a replacement for little or no cost to you.

Ok, thanks for clarifying what you have. Again, a trip to your local Apple Store should get this sorted out for you.
