Troubleshooting
The earbuds are turning on, but fail to connect to my device?
To connect your earbuds to your device, please remove the insulating films on the charging case and check that Bluetooth is enabled. If the earbuds still don't connect, try resetting them or contact us for assistance.
What to do if one earbud is silent or has low volume?
If the earbud's LED is lit, carefully clean the dirt from the speak mesh using a toothpick or cotton swab dipped in alcohol. Try to reset the two earbuds and reconnect. If the issue persists, please contact us for assistance.
How to resolve noise issues
Please choose suitable ear tips, rotate earbuds for a snug fit. Note that slight background noise in quiet environments in ANC mode is normal for all kinds of ANC earbuds.
What to do if the other person cannot hear clearly during a call?
Please adjust the position of the earbuds to ensure that the voice microphone is pointing towards the direction of the speaker's voice. Ensure the Bluetooth device uses the earbud's microphone for calls.
What to do if the earbuds fail to connect to the app?
Ensure Bluetooth connection and Location permissions are enabled for the app. These permissions do not involve any privacy information. You can also download the latest version of the app or uninstall and reinstall it if needed.
What to do if the audio quality does not meet your expectations?
We suggest personalizing your audio settings according to your preferences in the EarFun Audio app's EQ settings.
Why is the connection not stable and cuts out intermittently?
Please check for any objects obstructing the earbuds and the Bluetooth device, and avoid any potential radio or Wi-Fi interference. While the earbuds have a maximum range of 49 feet (15m) without obstacles, the actual range may vary depending on usage and the environment.
