Check the Bluetooth Pairing SettingsSometimes Bluetooth might simply be turned off on your phone or device. The icons that indicate whether Bluetooth is on or off can be difficult to see, or they might be hidden. If your device has a Bluetooth settings screen that allows fine control of Bluetooth behavior, you should ensure that Bluetooth is “connectable.” If your device does not have such a control screen, you can assume that the default behavior of the Bluetooth device is “connectable” and you don’t need to look for a way to enable this feature.
Turn it off and on againRestarting the affected device or devices, should almost always be your first troubleshooting step as it can fix a surprising number of issues. You should restart both your headphones and your phone for the best chance of this working.
Make sure Bluetooth is enabledA lot of phones have a quick access button to disable Bluetooth. Even though it’s unlikely, you should check your phone to make sure that you haven’t accidentally turned Bluetooth off in your pocket or bag.
Disconnect and reconnectTry disconnecting and reconnecting the Bluetooth connection between your phone and headphones. If that doesn’t work try unpairing them, then pairing them again.
Try different devicesThe best way to work out which device is causing the issue is to try them both with different devices. You should try connecting the Bluetooth headphones to another Bluetooth device, such as a computer as well as connecting your phone to another Bluetooth headset or speaker.
Recharge your devicesBattery power is obviously needed for both your phone and headphones to run. Check that they both have enough power. If your headphones don’t have a battery indicator, a few minutes of charging should be enough to identify if the battery charge was the issue.
Clear Bluetooth cache and dataIf none of these fixes work, you could try clearing your Bluetooth settings entirely. To do so, open the apps list in your phone’s settings app and tap on “Bluetooth”. If Bluetooth doesn’t appear in the list, you may need to enable “Show system apps”. To do so tap on the triple-dot icon in the top-right corner then select “Show system apps”.
