Sound Quality

Has Active Noise Cancellation (Noise Control)

Anker Soundcore Liberty 3 Pro
Bowers & Wilkins PI7

Active noise cancellation utilises advanced technology to actively cancel noise. 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 adding -1 (inverted noise) to make zero which results in a reduced level of noise.

The Bowers & Wilkins PI7 have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
