The earhook will turn off. ② Later it will turn on automatically to start the TWS pairing (left and right earhook pair with each other). Once the TWS pairing succeeds, the indicator light in the middle of the case will flash in red and white alternately. Under this state, the UTWS3 can be searched for and connected to. After the connection succeeds, it can be used normally. (Notes: First make sure the TWS pairing is successful. Otherwise the UTWS3 can not be discovered by any Bluetooth devices.)

(Only the name of the Master channel will be displayed on the list). ② When pairing, there will be 2 dialogues popping up. Click "Yes" successively to complete the pairing. (Bluetooth devices supporting TWS+ only need to pair once).

The FiiO UTWS3 can be controlled by the FiiO Control APP. Go to the APP market, searching for "FiiO Control" to download it. EQ setting, OTA upgrade, volume adjustment and many other features are all available in FiiO Control.
