ANC makes use of advanced kind of tech to reduce ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) to make zero therefore "diluting" the noise.
Nothing Ear 2 have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
The Anker Soundcore Liberty 3 Pro too have Active Noise Cancellation which makes either of the earbuds ideal for flights and morning commutes. Each operate with different noise cancellation settings, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.
