I tried to share my Apple AirPods with a friend of mine just like I did many times before but encountered issues with pairing. It didn't function as anticipated. How can I pair them?

Apple suggests a first aid guideline for its users if they encounter difficulties connecting their AirPods or AirPods Pro to their iPhone, or iPad. There is high possibility one of these will work but it may not be solved either. In that case, you should contact Apple support and share your challenges at Xolvie.
• Ensure your iPhone or iPad is running the latest iOS or iPadOS version.
• Place both AirPods in the charging case, ensuring they are charging.
• Confirm that Bluetooth is enabled by going to Settings > Bluetooth.
• If your AirPods are connected but not working, proceed to the next step.
• Close the lid of the charging case, wait for 15 seconds, and then reopen it.
• Press and hold the setup button located on the back of the charging case for up to 10 seconds. The status light on the front of the case should flash white, indicating that your AirPods are ready to connect.
• While keeping the charging case open and AirPods inside, hold it near your iPhone or iPad.
• Follow the on-screen instructions displayed on your iPhone or iPad.
• If you still encounter connectivity issues, consider resetting your AirPods or reaching out to Apple Support for further assistance.
