BEFORE YOU START
Make sure the earbuds are fully charged. Do this by
charging the earbuds in the charging case. Also plug
the USB-C charging cable into the USB-C port on the
charging case. Plug the other end of the cable into a
power source and charge until all 4 LED lights on the
charging case are stable.
PAIRING EARBUDS AND DEVICE
1. Take out the earbuds from the charging case.
The earbuds will automatically power on and pair
with each other. When blue/red lights flash alterna-
tely, the earbuds are ready to pair with your device.
2. Turn on the Bluetooth function on your device. Select
Defunc TRUE BASIC in the Bluetooth list to pair the
earbuds with the device. The earbud lights turn off
when the earbuds are paired. The earbuds will
automatically pair with a previously connected device
when powered on again.
POWER ON
There are two ways to turn the earbuds on:
1. Open the charging case and take out the earbuds for
auto-power on.
2. Press each earbud for 3 seconds until you hear the
on-sound.
The earbuds will also auto-pair with each other when
you power on.
POWER OFF
There are two ways to turn the earbuds off and one way
they auto-power off:
1. Put the earbuds back in the charging case and close
the cap.
2. Press either earbud for 5 seconds until you hear the
off-sound or see the LED lights flash 2 times.
3. Auto-power off will be activated after 5 minutes
without a connected device.
TOUCH CONTROL FUNCTIONS
Power on: Press each earbud for 3 seconds to power
on. (Please note: If you have just taken the earbuds out
of the charging case, they have already powered on.)
Power off: Press either earbud for 5 seconds to power
off. The easiest way though is to put the earbuds back
in the charging case and close the cap. Auto-power off
will be activated after 5 minutes without a connected
device.
Play/pause: Double-tap either earbud.
Next track: Press the right earbud for 2 seconds.
Previous track: Press the left earbud for 2 seconds.
Volume increase: Tap the right earbud once.
Volume decrease: Tap the left earbud once.
Answer/end phone call: Double-tap either earbud.
Reject call: Press either earbud for 2 seconds.
Voice assistant: Tap either earbud three times to
activate/deactivate.

CHARGE THE EARBUDS
Make sure that the charging case has battery life.
Put the earbuds in the charging case. Close the cap.
CHARGE THE CHARGING CASE
Plug the USB-C charging cable with the USB-C
port on the charging case. Plug the other end into
a power source.
LIGHTS ON THE CHARGING CASE
Each light equals 25% battery life on the charging case.
When each 25% is reached, the corresponding light
becomes stable, and the next starts flashing. When
charged to 100%, all 4 lights are stable.
GENERAL TIPS
• 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 will
last longer.
• Pause between each touch control command, e.g.
wait 1 second between each volume control tap to
further increase/decrease volume.
• To extend your listening experience, listen with one
earbud at a time. Let the other earbud charge in the
charging case.
WARNING
• Do not attempt to repair the earbud. A faulty repair
may lead to fire, electronic breakdown or a damaged
product.
• 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.
• Do not use the earbud in thunderstorm weather to
avoid abnormal earbud behavior and the risk of shock.
• Do not wipe the earbud with oil or other volatile
liquids.
• Do not wet the earbud.
