Earbuds are unresponsive or they are not able to charge

I went to use my earbuds yesterday and neither one would turn on and give me any kind of signal or connection to the phone or any other device. The case is charging fine and i tried all the resets that are supposed to help including trying the factory reset but the case never showed the lights like it was supposed to for that which i assume means the earbuds are not charged. Did both batteries go bad at the exact same time or is something else going on here?
