• Restart AirPods for use with iPhone
• We understand that your AirPods are not clogged. However, we'd like to make sure that they are clean as well as the case: How to clean your AirPods, AirPods Pro, AirPods Max, and EarPods
• Be sure your iPhone is running the latest software version: Update iOS on iPhone
