1. When connected to multiple devices, the earphones will prioritise reconnecting with the last device connected upon powering on again. Please confirm if the last device you used the earphones with is the one you are currently using.
2. If the earphones leave the charging case and don't find the last connected device within 1 minute, they will enter a timeout state. To exit it, place the earphones back into the case, close the lid for 5 seconds and then reopen to initiate a new connection.
3. Perform a factory reset by holding the function button on the charging case for 10 seconds or more, and then pair the earphones again.
4. If the issue remains unresolved, please download and update to the latest software using the Nothing X App.
Note: All device customisations are already integrated into the settings of Nothing OS version 1.1.4 and higher. Please keep the Nothing X app updated via the Google Play Store.
