i found the solution; Even when you recently bought AirPods, you need to update its FIRMWARE! Then it will work perfectly.
Apple doesn't currently provide a way to manually update the firmware on AirPods or AirPods Pro, opting instead for an automatic update process.
But Apple won't just install the firmware update willy-nilly (if your AirPods died mid-update it could cause all sorts of problems); you'll need to make sure of the following:
- Your AirPods must be in the charging case.
- The charging case must be plugged in and charging.
- An iOS device that's been connected to your AirPods must be nearby.
Once all of those conditions are met, the firmware update should automatically begin at some point.
Now, while you can't trigger a firmware update with a button press or tap, you can check what firmware version your AirPods are running and view some other interesting information about the wireless earbuds. Here's how:
How to check your AirPods' firmware version
- Make sure your AirPods are connected to your iOS device (open the charging case or put your AirPods in your ears).
- Launch the Settings app on your iOS device.
- Tap General.
- Tap About.
- Scroll down and tap AirPods or AirPods Pro.
- Check the number next to Firmware Version to see what firmware version your AirPods are running. Google to know what is the current latest version and see if it matches
