ANC uses advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The Jabra Evolve2 Buds have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
