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

Take out the earbuds from 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 AIR 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:

Open the charging case and take out the earbuds for auto-power on.
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:

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 the LED lights flash 2 times.
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.
