Chosen Solution
The right earbud stopped playing sound.When I place it in the charging tray though, the little LED still lights up, so I assume it is still charging. That being said, my bet is that it’s the speaker that stopped working…Anybody else had the same problem and was able to fix it?
Make sure that the contacts in the case and on the earbud are clean and are making contact with one another and make sure that your phone can see both earbuds.
