Adjusting the Headband:
• In order to achieve maximum comfort and noise cancellation,
the headband should be adjusted to properly fit your head
with the ear cups sitting comfortably over your ears.
Charging the Headphones:
Prior to use, charge your i9BT headphone unit by connecting the
included charging cable into a USB power outlet (such as USB
chargers or computer USB ports) and plug the other end into
the headphone's micro USB charging port.
The LED indicator will light up red showing that the unit is being
charged. When charging is complete, the red LED indicator will
turn off.
Active Noise Cancelling Mode
• Adjust the volume on the headphones.
• To power ON the noise cancelling function, set the ON/OFF
switch to ON. The Noise Cancelling LED indicator will light up
in blue.
Note: After you turn ON the power, you might hear a slight
hissing noise. This is a normal function and will cease after a
few seconds.
• When the batteries are running low, the Noise Cancelling LED
indicator will become dim.
• Once the battery is fully drained, the active noise cancelling
feature will turn off, but the audio signal from the music player
will continue to transmit.
• In quiet environments where noise cancellation is not required,
the i9 can also be used like conventional headphones, without
the use of batteries.
• When not in use, switch OFF the POWER to extend battery life.
