Sennheiser CX 500BT
Sennheiser Momentum True Wireless 3

ANC uses more advanced kind of tech to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) then adding -1 (inverted noise) to make zero resulting in a reduced level of noise.

Sennheiser CX 500BT have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
