TURN ON ACTIVE NOISE CANCELLATION AND
TRANSPARENCY MODE
The earbuds have 3 sound modes:
1. Active noise cancellation (ANC) mode actively cancels surrounding noise.
2. Transparency mode lets surrounding sounds into the earbuds.
3. Normal mode gives basic sound. It is the default when the earbuds
are turned on.
Press the right earbud for 3 seconds to switch from one sound mode
to another.
GENERAL TIPS FOR TRUE WIRELESS EARBUDS
• Because of interference with other Bluetooth devices, the earbuds
can get disconnected from each other. If you experience this
problem, put the earbuds in the charging case and close the cap.
After a few seconds, open the cap and start using the earbuds again.
• Hold the earbud stem when putting or adjusting the earbuds in
your ears. This way you avoid touching the sensitive touch area which
controls different functions.
• The volume affects the capacity of the battery. If you play your music
with lower volume, the battery life will last longer.
• Pause between each touch control command, e.g. wait 1 second
between each volume control tap to further increase/decrease volume.

earbuds in the charging case until all 4 blue lights on the charging
case are lit for 5 seconds and then turn off.
2. Open the charging case. The earbuds will automatically power on and
pair with each other.
3. When blue/red lights flash alternately, the earbuds are ready to pair
with your device.
4. Turn on the Bluetooth function on your device. Select Defunc TRUE
MUTE in the Bluetooth list to pair the earbuds with the device. Take out
the earbuds.
• The earbud lights turn off when the earbuds are paired.

when taken out of the charging case again.

red lights flash 3 times.
