Active noise cancellation makes use of more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (inverted noise) giving 0 which results in a reduced level of noise.
JBL Live Free 2 have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to overcome background sounds.
The JBL Live Pro 2 too have Active Noise Cancellation which makes both earbuds ideal for flights and rush hour travels. The JBL Live Free 2 and JBL Live Pro 2 work with different noise cancellation modes, pick the setting that you prefer for commute or that suites your chill time.
