1. The earphones will automatically disconnect when the Bluetooth connection exceeds the range. If you return to the connection range within 10 minutes, they will automatically reconnect successfully. If they stay outside of the connection range for more than 10 minutes, they will enter a timeout state without a connection. You can manually reconnect them by placing the earphones into the charging case, closing the charging case for 5 seconds, and then opening the charging case to power on the earphones and initiate the connection again.
2. Long-press the Smart Dial and function button for 5 seconds and reset to factory settings, complete when the indicator light flashes red for 10 seconds. Then re-pair for use.
3. If the issue remains unresolved, please download and upgrade to the latest version of the Nothing X App and try again.
