Common questions about manuals, registration, and support for this brand.
Take the newly purchased earbuds out of the charging case. They will automatically turn on and enter Bluetooth pairing mode (often indicated by a flashing white or blue light). Open the Bluetooth settings on your mobile device, search for your FIIL earbud model, and click to connect.
You can download the fiil+ Global Edition App from the Apple App Store or Google Play Store. Once your earbuds are connected to your phone via Bluetooth, open the app to configure advanced settings, customize EQ profiles, enable full control mode, and check battery levels.
Check that the charging case has battery power. Ensure the USB-C cable is securely connected and use a standard 5V adapter. Clean the charging contacts on both the earbuds and inside the case to remove any debris or wax buildup. If exposed to extreme temperatures, allow the earbuds to return to room temperature before attempting to charge.
Ensure the earbuds are fully charged and powered on. Check that the volume on both your earbuds and your connected device is turned up. Verify that the earbuds are actively paired and connected. If problems persist, disconnect and re-pair the Bluetooth connection.
On most FIIL earbud models, you can control the volume directly from the touch panels after enabling 'Full Control Mode' in the fiil+ app. Typically, tapping the left earbud once increases the volume, and tapping it three times decreases the volume.
