ANC makes use of more advanced kind of tech to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after inverts the soundwaves to counter it. In simple terms, it's like having +1 (noise) and producing -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
Sennheiser CX 500BT have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to overcome background noise.
