ANC uses more advanced technology to reduce ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal to cancel it out. Simply put, it's like having +1 (noise) and producing -1 (inverted noise) to make zero thus "diluting" the noise.
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 Bose QuietComfort Earbuds II too have Active Noise Cancellation making either of the earbuds ideal for flights and rush hour commutes. The OnePlus Buds Z2 and Bose QuietComfort Earbuds II operate with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that suites your chill time.

Driver Unit Size
Bose QuietComfort Earbuds II
9.3mm
OnePlus Buds Z2 11mm
The OnePlus Buds Z2 driver unit is 11mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the device, the unit size corellates with the sound produced by the device.
Bose QuietComfort Earbuds II driver unit is 9.3mm in diameter,
which implies that they have a smaller driver unit than that of OnePlus Buds Z2 by 1.7mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Bose QuietComfort Earbuds II
20Hz
OnePlus Buds Z2 20Hz
The OnePlus Buds Z2's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Bose QuietComfort Earbuds II's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
Highest Frequency
Bose QuietComfort Earbuds II
20000Hz
OnePlus Buds Z2 20000Hz
OnePlus Buds Z2's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device makes high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Bose QuietComfort Earbuds II's highest frequency is at 20000Hz, this means that
both devices generate equal treble
