6. Troubleshooting

6.1 Earbuds Not Pairing or Connecting

• Re-seat Earbuds: Place both earbuds back into the charging case, close the lid, wait 5 seconds, then open the lid again to force them to re-enter pairing mode.
• Device Bluetooth: Ensure Bluetooth is enabled on your device and that the FW5 is selected.
• Forget Device: On your device, 'forget' or 'unpair' the FiiO FW5, then attempt to pair again from scratch.
• Reset Earbuds: Refer to the FiiO Control app or FiiO's official support for specific hard reset instructions if standard pairing fails repeatedly.

6.2 Low Volume Output

• Check Device Volume: Ensure the volume on your connected device is turned up.
• Check Earbud Volume: Adjust volume using the physical buttons on the earbuds.
• FiiO Control App: Open the FiiO Control app and check the 'Headphone Volume' and 'Volume of tones' settings. Adjust the volume gain if necessary.
• Eartip Seal: Ensure a proper seal with the eartips. A poor seal can significantly reduce perceived volume and bass response.

• Case Lid: Ensure the charging case lid is fully closed when storing the earbuds.
• Firmware: Check for firmware updates via the FiiO Control app, as battery management improvements are often included in updates.
