ANC uses advanced kind of tech to reduce ambient sounds. How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal to counter it. In simple terms, it's like having +1 (noise) then producing -1 (inverted noise) giving zero which results in a reduced level of noise.
Bose QuietComfort Earbuds 2 have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background noise.
Bowers & Wilkins PI7 too have ANC making either of the devices ideal for plane rides and rush hour commutes. Each work with different noise cancellation types, pick the setting that you prefer for commute or that enhances your relaxation time.

Driver Unit Size
Bose QuietComfort Earbuds 2
9.3mm
Bowers & Wilkins PI7 9.2mm
The Bose QuietComfort Earbuds 2 have a unit size of 9.3mm in diameter, the bigger the unit the more powerful, and can produce better bass.

Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which implies that they have a smaller driver unit than that of Bose QuietComfort Earbuds 2 by 0.1mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Bose QuietComfort Earbuds 2
20Hz
Bowers & Wilkins PI7 10Hz
The Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low audible frequencies and if it makes any changes to the signal while at it.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this implies that
Bowers & Wilkins PI7 produce a juicier bass than the Bose QuietComfort Earbuds 2
Highest Frequency
Bose QuietComfort Earbuds 2
20,000Hz
Bowers & Wilkins PI7 20,000Hz
The Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component produces high audible frequencies and if it makes any adjustments to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices can generate equal treble
