Place both earbuds in the charging case and keep the lid open. Press and hold the pairing button for 10 seconds until the three indicators flash white rapidly in sequence. The bottom indicator will then briefly turn red. Once the red light goes out, the earbuds will automatically enter pairing mode, indicating that the factory reset has been completed successfully.
Note: If your earbuds support recording, a factory reset will delete all unsynced recordings saved on the earbuds. Uninstalling or reinstalling the Nothing X App will also erase all recordings in the app. Please back up important recordings first before performing a factory reset, uninstalling or reinstalling the app to avoid data loss.
