ANC uses more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) to make 0 hence "diluting" the noise.
OnePlus Buds Pro 2 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background noise.
The Anker Soundcore Liberty 3 Pro too have ANC making either of the devices ideal for flights and morning travels. Each work with different noise cancellation modes, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.
