ANC stands for ‘Active Noise Cancellation’ and it is a technology used in earphones/headphones to actively reduce background noise. This provides a better audio experience for the listener as they can focus more on the music without it competing with background noise. ANC earphones also allow the listener to listen to music at lower volumes because they don’t have to increase the volume so much in order to block out background noises.
Before we go into detail about how it works, let us start by understanding the audio frequencies we can hear.
On average most humans can hear audio frequencies ranging from 20Hz to 20Khz.
In order to reduce lower frequencies your earphones need ‘active noise cancellation’ technology or ‘ANC’ for short. ANC earphones/headphones are able to reduce lower frequencies by around 20-40db which makes a noticeable difference, especially when combined with the passive noise cancellation of the earphones themselves.
ANC works by using microphones to pick up low-frequency noise and then by neutralisingthat noise before it reaches the ear. The headset generates a sound that’s phase-inverted by 180 degrees to the unwanted noise, resulting in the two sounds cancelling each other out.

Our Hezire H-Budz ANC features Active Noise Cancellation with up to 25 dB of noise reduction for a more immersive listening experience. As an added benefit, we also include ‘transparency’ mode which does the opposite of ANC by allowing background noise to enter the earphone more freely. This is especially useful if you are using your earbuds in urban environments where you need to be aware of traffic and other hazards. You can conveniently switch between regular (no ANC/transparency) mode, ANC mode and Transparency mode simply by pressing and holding the touch control located on the earbud.
