Hi panthway,
If you haven't done so yet, restart the device your AirPods are connected to. Although simple, restarting can help correct some unexpected issues. It's also a good idea to make sure that the device is running the latest software version. If an update is available, it's a good idea to create a backup before installing it. If you're using your AirPods with an Apple device follow these steps:
Update your iPhone or iPad
Update macOS on Mac

Another step that will help with isolating the behavior is testing with a different device. This will tell you if the issue is stemming from the AirPods or possibly the device they're connected to.
If you need more help, reach out to Apple Support directly so they can look into this with you further. They can be contacted here: Get Support or by calling the most applicable phone number from this list: Contact Apple for support and service.
