Active noise cancellation utilises more advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and generates a mirror signal to counter it. Simply put, it's like having +1 (noise) then adding -1 (counter sound by the device) giving zero therefore "diluting" the noise.
The JBL Reflect Aero TWS have ANC allowing you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to outcompete background sounds.
The JBL Live Free 2 too have Active Noise Cancellation which makes both earbuds ideal for flights and morning travels. Each operate with different noise cancellation settings, pick the noise cancellation type that you prefer for commute or that enhances your chill time.
