Active noise cancellation uses more advanced kind of tech to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving 0 therefore "diluting" the noise.
Huawei FreeBuds 5i have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to overcome background sounds.
The OnePlus Buds Z2 too have ANC making both earbuds ideal for plane rides and morning travels. The Huawei FreeBuds 5i and OnePlus Buds Z2 work with different noise cancellation settings, pick the noise cancellation type that suits your commute or that suites your relaxation time.

Huawei FreeBuds 5i
20Hz
OnePlus Buds Z2 20Hz

both devices make sound with equal bass
Highest Frequency
Huawei FreeBuds 5i
40000Hz
OnePlus Buds Z2 20000Hz
The Huawei FreeBuds 5i's highest frequency is at 40000Hz, high-frequency response indicates how well an audio component makes high recognizable frequencies and if it adjustments to the signal while at it.
