ANC utilises more advanced technology to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 hence "diluting" the noise.
Sennheiser CX 500BT have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
The Anker Soundcore Liberty 3 Pro too have ANC making either of the earbuds ideal for plane rides and rush hour commutes. The Sennheiser CX 500BT and Anker Soundcore Liberty 3 Pro operate with different noise cancellation modes, pick the noise cancellation type that suits your travel or that suites your relaxation time.
