Hi airp0ds,
Thanks for coming to Apple Support Communities for help today.
It sounds like you may be describing separation alerts. This article will provide more information: Get separation alerts if you leave your AirPods behind.
Here's how you can check to see if the alerts are turned on:
"Turn on separation alerts on iPhone, iPad, or iPod touch
- Open the Find My app, tap Devices, then tap the name of your AirPods.
- Below Notifications, tap Notify When Left Behind.
- Turn on Notify When Left Behind, then follow the onscreen directions.
- To add a trusted location, choose a suggested location, or tap New Location, select a location on the map, then tap Done.
- Tap Done."
Let us know more details if that doesn't explain it.
Have a fantastic day!
