Apple headphones are a very popular audio device, but sometimes we may need to restore it to factory settings to fix certain issues or erase personal data. Here are some simple steps to help you restore your Apple headphones to factory settings.
First, make sure that your Apple earbuds have been disconnected from the device and that there are no other Bluetooth devices paired with them. Then press and hold the power button on the headphones, releasing the button when the "Forget this device" option appears on the screen.
Next, open the settings menu of the device you want to connect to, such as your iPhone or iPad. Find your Apple earbuds in the Bluetooth tab and tap on the right to reveal more information icon (usually a small circle i). In the new page, scroll down and select "Forget This Device".
Once you have completed the above steps, restart your device such as your iPhone or iPad. Then go to the Bluetooth option in the settings menu again and make sure you are in a state where you can discover and pair other Bluetooth devices.
Finally, before opening the charging case and putting the Apple earbuds in it, look to see if there is a small button at the bottom of the charging case. Press and hold the button for about 15 seconds until the light starts flashing.
This completes the Apple headphones factory reset process. Note that this action will erase all personal data and configuration information associated with that particular device and cannot be undone. So, before you do this, be sure to confirm and be ready to reconfigure which device you want to connect to using them.
Summary: It is easy to restore Apple earbuds to factory settings by pressing and holding the power button, forgetting the Bluetooth connection, restarting your phone, and long-pressing the bottom button of the charging case.
