The earbuds automatically disconnect when the Bluetooth connection exceeds the range. If you return to the connection range within 10 minutes, they automatically reconnect. If they stay outside of the connection range for more than 10 minutes, they enter a timeout state without a connection. To reconnect, try one of the following options:
1. Reconnect them manually. Simply place the earbuds into the charging case, close it for 5 seconds, and then open the charging case to power on the earbuds and initiate the connection.
2. Long-press the function button on the charging case for 5 seconds and reset to factory settings – the reset is complete when the indicator light flashes red for 10 seconds. Then pair again.
3. If the issue remains unresolved, please download and upgrade to the latest version of the Nothing X app and try again.
