Has Active Noise Cancellation (Noise Control)

Bowers & Wilkins PI7 ✓
Active noise cancellation makes use of advanced kind of tech to actively counter noise. How it works, it studies the sound pattern of incoming noise and then inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) giving zero thus "diluting" the noise.
Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the device volume to overcome background noise.
Samsung Galaxy Buds Pro too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation settings, pick the setting that suits your travel or that enhances your chill time.

Bowers & Wilkins PI7 stay tightly in place, this creates an acoustic seal that reduces background noise and also prevents the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction which means that they limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Samsung Galaxy Buds Pro
11mm
Bowers & Wilkins PI7 9.2mm
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size corellates with the loudness of the earbuds.
Samsung Galaxy Buds Pro driver unit is 11mm in diameter,
making them have a larger driver unit than that of Bowers & Wilkins PI7 by 1.8mm
, 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 deliver better quality sound.
Lowest Frequency
Samsung Galaxy Buds Pro
20Hz
Bowers & Wilkins PI7 10Hz
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
Samsung Galaxy Buds Pro's lowest frequency is at 20Hz, this means that
Bowers & Wilkins PI7 make sound with a juicier bass than the Samsung Galaxy Buds Pro
Highest Frequency
Samsung Galaxy Buds Pro
20000Hz
Bowers & Wilkins PI7 20000Hz
The Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device generates high recognizable frequencies and if it makes any adjustments to the signal while at it.
Samsung Galaxy Buds Pro's highest frequency is at 20000Hz, this means that
both devices can generate equal treble
