Active noise cancellation utilises advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 resulting in a reduced level of noise.
The JBL Tune Flex have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to outcompete background sounds.
