ANC ACTIVE NOISE CANCELLATION MODES
The ANC modes offer 3 different listening
experiences. Press the ANC button to cycle
through the different modes below.
1. Noise Cancelling (NC) Mode:
This mode isolates your listening
experience specifically to sound coming
through the headphones and helps
blocking unwanted outside noise.
NC mode is automatically activated
by default when the headphones are
powered on. When NC mode is active, the
Right LED indicator of the headphones
turns solid GREEN.
2. Ambient Sound Mode:
Ambient mode allows you to listen to
the sounds around you through the
built-in microphones even while wearing
the headphones.
To enter Ambient mode, press the ANC button once and the voice prompt
"Ambient sound" is heard, the Right LED indicator of the headphones will
turn solid WHITE.
Note: Ambient mode allows you to hear background noise clearer, such as
important announcements and street traffic. However, certain sounds may
not be heard well depending on the environment. Be cautious in places where
an inability to hear ambient sound would be dangerous.
3. Ambient Sound and NC OFF:
Press the ANC button twice and the voice prompt "Ambient sound and noise
cancelling off" is heard, the Right LED indicator will turn off.
To turn NC mode back on, press the ANC button again.
