✓
Bowers & Wilkins PI7 ✓
Active noise cancellation uses more advanced kind of tech to reduce ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make zero therefore "diluting" the noise.
Bose QuietComfort Earbuds II have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to overcome background noise.
The Bowers & Wilkins PI7 too have Active Noise Cancellation which makes both earbuds ideal for flights and morning travels. The Bose QuietComfort Earbuds II and Bowers & Wilkins PI7 operate with different noise cancellation settings, pick the noise cancellation type that suits your travel or that suites your chill time.

Driver Unit Size
Bose QuietComfort Earbuds II
9.3mm
Bowers & Wilkins PI7 9.2mm
The Bose QuietComfort Earbuds II have a unit size of 9.3mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is the component that produces sound in the device, its size determines the loudness of the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort Earbuds II by 0.1mm
, as many tend to believe 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 II
20Hz
Bowers & Wilkins PI7 10Hz
Bose QuietComfort Earbuds II's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low audible frequencies and if it alters the signal on its way through.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that
Bowers & Wilkins PI7 produce a juicier bass than the Bose QuietComfort Earbuds II
Highest Frequency
Bose QuietComfort Earbuds II
20000Hz
Bowers & Wilkins PI7 20000Hz
Bose QuietComfort Earbuds II's highest frequency is at 20000Hz, high-frequency response shows how well an audio component produces high human frequencies and if it changes to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20000Hz, this means that
both devices produce equal treble
