Active noise cancellation makes use of 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 cancel it out. Simply put, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) giving 0 which results in a reduced level of noise.
OnePlus Buds Pro 2 have ANC enabling you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the earbuds volume to outcompete background sounds.
The Sony WF 1000XM4 too have ANC which makes either of the devices ideal for flights and rush hour commutes. Each work with different noise cancellation modes, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.

which implies that they have a smaller driver unit than that of OnePlus Buds Pro 2 by 5mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
