Question Onn Bluetooth earbuds not charging

Aug 2, 2021
I recently purchased a pair of Onn Bluetooth earbuds, and they've been working great for a while. But as of yesterday the right earbud has stopped working. The left works fine, but the right won't charge or connect. I leave them charging for a few hours a day and while the left charges properly, the right earbud refuses to charge. I've even tried using another case to try and charge, yet it still will not. How would I be able to fix this issue?
