Active noise cancellation utilises advanced technology to reduce ambient sounds. How it works, it detects and analyzes 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 producing -1 (counter sound by the device) giving zero therefore "diluting" the noise.
Nuraphone NuraTrue have ANC allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
Xiaomi Redmi Buds 4 Pro too have ANC making either of the earbuds ideal for flights and morning commutes. The Nuraphone NuraTrue and Xiaomi Redmi Buds 4 Pro work with different noise cancellation settings, pick the mode that you prefer for travel or that enhances your chill time.
