Troubleshooting Common Connection Issues

Even with a simple process, occasional hiccups can occur. Here are some common issues and how to address them:

Headphones Not Appearing in Bluetooth List

If the WH-CH720N isn’t showing up on your iPhone’s Bluetooth list, try the following:

Ensure the headphones are in pairing mode: Double-check that the indicator light is flashing blue. If not, repeat step 2 above, holding the power button for the full 7 seconds.
Restart your iPhone’s Bluetooth: Toggle the Bluetooth switch OFF and then ON again in the Settings app. This refreshes the Bluetooth connection.
Move closer to the iPhone: Bluetooth signals have a limited range. Make sure the headphones are within a few feet of your iPhone during the pairing process.
Check for interference: Other electronic devices can sometimes interfere with Bluetooth signals. Move away from potential sources of interference like microwaves or other Bluetooth devices.

Headphones Connected but No Sound

If your iPhone indicates that the headphones are connected, but you’re not hearing any audio, consider these solutions:

Check the volume: Ensure the volume on both your iPhone and the headphones is turned up. Use the volume controls on the headphones or the iPhone’s side buttons.

Disconnect and reconnect: Sometimes, a simple disconnect and reconnect can resolve the issue. In your iPhone’s Bluetooth settings, tap the “i” icon next to “WH-CH720N” and select “Forget This Device”. Then, repeat the pairing process from the beginning.
