ANC utilises more advanced kind of tech to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving 0 which results in a reduced level of noise.
The OnePlus Buds Z2 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
The Samsung Galaxy Buds 2 Pro too have ANC making both earbuds ideal for flights and rush hour travels. The OnePlus Buds Z2 and Samsung Galaxy Buds 2 Pro operate with different noise cancellation modes, pick the noise cancellation type that suits your commute or that suites your chill time.
