6.4 ACTIVE NOISE CANCELLATION (ANC)
The headset uses Active Noise Cancellation (ANC)
to reduce outside disturbance to a minimum,
allowing you to fully focus on your work or call.
Additionally, sound quality is also boosted when
ANC is switched on. ANC is powered by the in-built
rechargeable battery. The battery will power ANC
for up to 24 hours, when not connected to the
controller.
Slide the Active Noise Cancellation switch to ANC
ON/ANC OFF.
