A：1. Confirm Pairing Steps are Correct: Press and hold the headphone power button for 5 seconds until the indicator light flashes alternately or you hear the voice prompt "Pair". Select the headphones in the Bluetooth list to complete the connection. If the connection still fails, continue to the next step.
2. Reset Headphones: Sometimes, resetting the headphones can resolve connection issues. Please refer to the reset instructions for your headphone model and follow the steps.
3. Clear Old Bluetooth Pairings: If the headphones have been previously paired with other devices, they may not connect correctly because the headphones may still be trying to reconnect to those devices. Remove the headphones from the Bluetooth list of previously connected devices or forget about them.
4. Pair Headphones Again: Press and hold the headphone power button for 5 seconds until the indicator light flashes alternately or you hear the voice prompt "Pair". If pairing fails, continue to the next step.
5. Test the Connection with Other Devices: If your headphones connect normally to other devices, the headphones themselves are working correctly. The problem may be with the compatibility or settings of the first device. In this case, we recommend contacting the device manufacturer for further assistance.
