Can't complete a Bluetooth pairing

Try the following steps if the Bluetooth® pairing fails:

1. Make sure that you follow these instructions before attempting to pair a device:
   • Make sure that the Bluetooth function is active both on the Headset and the smartphone.
   • Bring the Headset and the smartphone within 1 meter (3.3 feet).
   • Remove the Bluetooth pairings for devices other than the one you want to connect.
   • The Headset may already be connected to another device (such as a smartphone). Disconnect the Bluetooth settings for devices other than the device you want to connect.
   • For iOS 11: If the app frequently asks Turn Bluetooth on?, try the following from the Control Center.
     1. Turn off Airplane mode.
     2. Turn the Bluetooth settings OFF, then ON again.
   • For iOS 13.0 or later
     In the Settings menu, select Music Center and Headphones app, and allow access to the Bluetooth.
     
     Note: For iOS 14 or later, you should also turn on the Local Network for Music Center. The following illustration is an example of the Music Center settings.
     
2. Follow these steps to pair the Headset and the smartphone:
   1. On the smartphone, turn on the Bluetooth function.
   2. For a Truly Wireless headset, remove the earbuds from the charging case.
   3. Enter the Headset to pairing mode:
      • For Truly Wireless headsets: Hold your fingers to the touch sensor buttons until the headset indicators flash. When the headset enters pairing mode, the headset indicator lights will repeatedly flash blue or blue and red.
        
        Note: For WF-SP700N or WF-SP900, press the button on the Left side for about 7 seconds.
      • For Headband or In-Ear headsets: Press and hold the Power button until the headset indicators flash. When the headset enters pairing mode, the headset indicator lights will flash blue twice, or blue and red.
3. When the headset name appears in the Bluetooth settings on the smartphone, select the headset name, then the pairing is complete.
