Active Noise Cancellation (ANC) uses noise-cancelling speakers to reduce unwanted background noise.



The system is based on microphones that “listen” to the sounds outside and inside of the earphone, an ANC chipset inverting the soundwaves and a speaker inside the earphone cancelling the outside sound by the neutralising soundwaves. A bit like taking +2 outside and adding -2 inside to make zero.

Active noise cancellation can processed through the ANC chipset using either:


A feed-forward ANC system has a microphone which is placed on the outside of the earphone

a feed-back ANC system has a microphone which is placed on the inside of the earphone

a hybrid ANC system is a combination of a feed-forward and a feed-back ANC system


Noise Cancellation types

There are different types of setting based on the user usage scenario and let have a brief

Transparency Mode


Lets you easily tune back into the world around you, without switching off your music or taking your earphones out of your ears



Adjustable Active Noise Cancellation


Lets you change how much background noise you hear by manually adjusting noise cancellation levels. This is useful when you want to have full control.


This is how the ANC features and type of mode that users can use based on their requirements and that's all for the day guys and do share your insights about ANC features
