User Guide and Specifications
Power ON/OFF
The FiiO FW5 are true wireless Bluetooth earbuds designed for portable audio. The product includes the earbuds and a charging case.
Power On and Connect: When using the FW5 for the first time, opening the charging case activates the earbuds. The white indicator lights on both units will stay on for approximately 3 seconds, after which the FW5 will power on automatically and enter Bluetooth pairing mode. Your device can then search for and connect to "FiiO FW5". For subsequent uses, the earbuds will automatically reconnect to the last paired device upon powering on.
Charging When Powered Off: Place both earbuds into the charging case and close the lid. The FW5 will automatically power off and begin charging. A note advises to tear off the adhesive insulation paper on the metal contacts before the first use.
