Why didn't the headphones automatically reconnect to my device?

1. When the headphones have a connection history with multiple devices, they will prioritise reconnecting to the last connected device upon startup. Please confirm whether the device you are currently using was the last one connected to the headphones. 2. After powering on or exiting sleep mode, the headphones will attempt to reconnect for 1 minute. If reconnection is unsuccessful, they will enter pairing mode for 2 minutes. During this time, we recommend re-searching for the headphones on your device and connecting manually. If not connected within 2 minutes, the headphones will enter an unconnected state and require a manual press of the Bluetooth pairing button until the white LED starts flashing to enter pairing mode. 3. Please check if a USB-C Audio or 3.5mm cable is inserted. When a wired connection is detected, it will take priority, and the Bluetooth connection will be automatically disconnected. Once the cable is removed, the headphones will automatically trigger Bluetooth reconnection. 4. Press and hold the Bluetooth pairing button for 10 seconds or more to restore the headphones to factory settings, then re-pair them. 5. If the issue persists, please download and update to the latest firmware using the Nothing X App and try again. 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 in the Google Play Store.
