Active noise cancellation utilises more advanced kind of tech to actively counter noise. How it works, it studies the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) and adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
The OnePlus Buds Z2 have ANC enabling you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to overcome background noise.
The Samsung Galaxy Buds 2 Pro too have Active Noise Cancellation making both devices ideal for plane rides and morning commutes. The OnePlus Buds Z2 and Samsung Galaxy Buds 2 Pro work with different noise cancellation types, pick the setting that suits your commute or that suites your chill time.

Highest Frequency
Samsung Galaxy Buds 2 Pro
20000Hz
OnePlus Buds Z2 20000Hz
