Stereo Pairing

Take both earbuds out of the charging box. The earbuds will automatically power on. The left earbud will pair to the right earbud automatically. The light of the left earbud will flash red and blue alternately and the right earbud’s indicator light remains off.
The right earbud “BW-FYE4 ” is the earbud you need to pair your device to for stereo sound. Activate Bluetooth mode on your device, search for nearby devices, and then pair to “BW-FYE4.”

Mono Pairing

If you only want to use one earbud, take out the L or R earbud and Bluetooth pair your device to the corresponding side, “BW-FYE4” or “BW-FYE4 R”.

Troubleshooting

The earbud won’t pair with my device.

Confirm that the earbuds are powered on. If they are not powered on, put them back into the charging box and take them out again.
Confirm that the earbuds are in pairing mode.
In stereo mode, the indicator light of the left earbud flashes red and blue alternately, and the indicator light of the left earbud flashes blue slowly.
In mono mode, the indicator of the earbud flashes red and blue alternately. If not in pairing mode, please check whether the earbud has automatically paired to another device. If it is paired to another device, turn Bluetooth mode off or unpair the “BW-FYE4 /R” from the already paired device.
Confirm that the earbud is within the range of 10 meters.

Sound is only playing from one earbud in stereo mode.

Check that both earbuds have battery power remaining.
Long press to power off both earbuds. Then long press to power on both the earbuds simultaneously. Hold the Multi-function button until you hear a second audible tone. The process takes about 20s and completely clears the pairing list. Then, put the earbuds back into the charging box, and try the pairing process again. If there are any other signal abnormalities, do as above to reset the earbuds.
