The ear cups are marked with "L" and "R" to indicate the left and right sides
of the headphones. Be sure to put them on correctly to enjoy your audio as
originally intended and maximize your personal music experience.
Earphone Mounted Controls
The main controls are located on the rear part of the right ear cup. They are
used to control Volume, Noise Cancelling, and your smart device (tablet,
iPod) as needed.
Volume and Active Monitor
Slide up towards the + sign to increase the volume.
Slide down towards the – sign to lower the volume.
Press the button VOL/M to engage the Active Monitor and
reduce your current audio track by 30dB. This will enable you to
hear your surroundings, without leaving your personal space.
The described function only works in Active Noise Cancelling
mode. When activated, the surroundings will be amplified
through the headphones.
Active Noise Cancellation and Amplifier
The power modes use the internal (rechargeable) battery.
In Active Noise Cancelling mode, the "Noise Cancelling" feature
has been activated with the internal headphone amplifier. The
3-position Power Switch will be "GREEN".
In Active mode, the internal headphone amplifier is active. The
3-position Power Switch will be "BLUE".
In Passive mode (OFF), noise cancelling and amplifier are turned
off. No power is required as the headphones are powered by
your audio source. Note: Bluetooth connection will not work in
this mode.
Phone Function
If you receive a phone call during a listening session press the
Phone button to answer the incoming call and pause your
audio track. Once the call is complete, a single button press will
end the call and resume audio play. The call answer only works
when connected by Bluetooth. The player controls work when
connected by Bluetooth or USB to a PC.
When listening to a handheld music device such as an iPod, the
Audio Control Button can be used to change to the previous
track, the next track or pause and resume music without
reverting back to the controls of the handheld device.
Slide the button up for previous track.
Slide the button down for the next track.
