Please follow the following steps:
1. Make sure the earphone is fully charged.
2. Turn off and turn on Bluetooth on the phone/tablet again.
3. If the paired device or my device list already contains the name of the headset you want to pair (for example, FreeBuds 5), please click to cancel pairing or ignore this device as shown below; If there is no device name, please go directly to the next step.
4. put the two earphones into the box and keep the cover open, and press and hold the function key for more than 2 seconds (for FreeLace series earphones, press and hold the function key for 4-6s, and for FreeBuds SE 2, press and hold the touch area of the left and right earphones for 3 seconds or more at the same time), until the indicator light blinks and enters the pairing state.
5. open the settings to enter the bluetooth interface, restart bluetooth, and click the name of the headset in the list of available devices or other devices for pairing connection.
