Hello KOKOE11E,
Thanks for posting in the Apple Support Communities.
Unfortunately, there is no way to locate your AirPods without using the Find My app. If you can recall the area, you were in when they went missing, you might want to check Lost and Found or your local law enforcement agency to see if they were turned in.
Find your lost AirPods - Apple Support
If your AirPods are offline
If your AirPods are out of range or need to charge, you might see their last known location, "No location found," or "Offline."
You can't play a sound to find them, but you might be able to get directions to the location where they were last connected. If they do come back online, you get a notification on the iPhone, iPad, iPod touch, or Mac that you use with them.
Best wishes.
