DEFUNC TRUE AUDIO
Thanks for choosing Defunc TRUE AUDIO. Read this manual to optimize
your experience. Enjoy your new earbuds!
WHAT’S INCLUDED
• Defunc TRUE AUDIO earbuds
• Extra earplugs (size S/M/L in A3 and Q31 series)
• USB-C Fast charging case and cable
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.
