TURN ON ACTIVE NOISE CANCELLATION AND TRANSPARENCY MODE
The earbuds have 3 sound modes:
- Active noise cancellation (ANC) mode actively cancels surrounding noise.
- Transparency mode lets surrounding sounds into the earbuds.
- 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.
GET STARTED
- Make sure the earbuds are fully charged. Do this by charging the earbuds in the charging case until all 4 blue lights on the charging case are lit for 5 seconds and then turn off.
- Open the charging case. The earbuds will automatically power on and pair with each other.
- When blue/red lights flash alternately, the earbuds are ready to pair with your device.
- 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.
- The earbuds will automatically pair with a previously connected device when taken out of the charging case again.
POWER ON
There are two ways to turn the earbuds on:
- Open the charging case for auto-power on after about 1 second.
- Press each earbud for 3 seconds until you hear the on-sound or blue lights flash 3 times.
POWER OFF
There are two ways to turn the earbuds off and one way they auto-power off:
- Put the earbuds back in the charging case and close the cap.
- Press either earbud for 5 seconds until you hear the off-sound or see red lights flash 3 times.
- Auto-power off will be activated after 5-6 minutes without a connected device.
TOUCH CONTROL FUNCTIONS
Tap or press the earbud touch area to control different functions.
Switch sound modes: Press the right earbud for 3 seconds to switch from normal to active noise cancellation (ANC) mode, 3 seconds again to switch from ANC to transparency mode, and 3 seconds again to go back to normal mode. If the earbuds are turned off, normal mode will be the default when turned back on.
Power on: Open the charging case for auto-power on or press each earbud for 3 seconds.

-
Do not use the earbud in an environment where the temperature is below 0 °C or above 45 °C.

Avoid using a device indicator light near the eyes of children and animals.
