Active noise cancellation makes use of more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 resulting in a reduced level of noise.
The LG Tone Free Fit TF8 have ANC allowing 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 sounds.
The Sennheiser Momentum True Wireless 3 too have ANC making either of the devices ideal for plane rides and morning travels. Each operate with different noise cancellation types, pick the setting that you prefer for commute or that suites your relaxation time.
