To resolve the problem of the One AirPod Not Working, one of the effective solutions is to reset your Apple AirPods. Begin with charging the AirPods by putting them both into the charging case and closing the lid within a period of 30 seconds. Next, unscrew the lid, touch and release the setup button on the case until you see the LED light flash amber and then white. This will restart the AirPods. Then, reconnect them to your device. This, according to DeviceFixes, will fix some minor software glitches and sync problems, and will get both AirPods functional again without requiring professional service.
