Active noise cancellation uses advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern of incoming noise and after generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
The Nuraphone NuraTrue have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the earbuds volume to outcompete background noise.
