Active noise cancellation makes use of advanced kind of tech to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) and adding -1 (inverted noise) to make 0 hence "diluting" the noise.
Jabra Evolve2 Buds have Active Noise Cancellation 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 outcompete background sounds.
JBL Live Free 2 too have ANC making either of the devices ideal for flights and morning commutes. The Jabra Evolve2 Buds and JBL Live Free 2 operate with different noise cancellation modes, pick the mode that you prefer for commute or that suites your relaxation time.
