Active noise cancellation makes use of advanced technology to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
Jabra Elite 7 Pro have Active Noise Cancellation 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 noise.
