Three Pairs of Earbuds, All Somehow Stopped Working.

Three pairs of regular, apple earbuds (the ones with wires, not the fancy airpods)

Somehow, all three of them have no audio coming out of the left ear. It's nothing wrong with my phone settings, I've tried them with other devices and the left ear just won't work.

The earbuds are clean, I haven't damaged them on the outside in any way, and the right ear works. Can somebody recommend a fix? I want working earbuds ;-;
