Sometimes if your AirPods aren’t working correctly, like if only one of the AirPod is connecting or playing sound, a simple reset will resolve the issue. I had an issue where only my left AirPod or right AirPod would connect and not the other. I was able to fix this with a reset.
Reset AirPods
1. Make sure the AirPods are in the charging case and with the lid opened, hold the setup button for 15 seconds (the light will turn from white to orange).
