Using Active Noise Cancellation (ANC)
This headset provides attenuation of ambient noise using Active Noise Cancellation (ANC) technology. Special microphones
optimize speech and reduce background noise.
When "Adaptive ANC" is selected, active noise cancellation depends on the intensity of ambient noise. The active noise
cancellation can be strong if the ambient noise is high, or weak if the ambient noise is low. You can control the extent of
noise cancellation for the ANC Adaptive mode via the Smart Control app.
If you are in a noisy environment but would like to have your own quiet space, you can use the headset itself, disconnected
from any device, and simply benet from ANC. You can activate ANC if the battery is suciently charged and if the headset
is turned on.
Good to know about ANC
• Continuous uniform noise, such as motor or fan noise, is suppressed
• Speech or high-frequency noise is reduced
• If a slight noise in very quiet environments occurs: Deactivate ANC.
• If unusual whistling or beeping noises occur: Take the headset o and put it on again and check the t of the ear cups.
