Sony LinkBuds S ✓
Active noise cancellation makes use of advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
Bowers & Wilkins PI7 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to outcompete background noise.
The Sony LinkBuds S too have ANC making either of the earbuds ideal for plane rides and morning commutes. The Bowers & Wilkins PI7 and Sony LinkBuds S work with different noise cancellation modes, pick the setting that you prefer for commute or that enhances your chill time.

Bowers & Wilkins PI7 sit well in place, this creates an acoustic seal that tones down background sounds well as preventing the earbuds sound from leaking out .
Both Sony LinkBuds S, and Bowers & Wilkins PI7 have passive noise reduction this means that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
Sony LinkBuds S 5mm
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that produces sound in the earbuds, its size dictates the loudness of the device.
Sony LinkBuds S driver unit is 5mm in diameter,
which means that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 4.2mm
, as many tend to believe 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 can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
Sony LinkBuds S 20Hz
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well a particular audio device generates low audible frequencies and if it alters the signal on its way through.
Sony LinkBuds S's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 produce a juicier bass than the Sony LinkBuds S
Highest Frequency
Bowers & Wilkins PI7
20000Hz
Sony LinkBuds S 40000Hz
Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device makes high recognizable frequencies and if it makes any adjustments to the signal while at it.
Sony LinkBuds S's highest frequency is at 40000Hz, this means that
Sony LinkBuds S can produce a clearer and crispier treble than the Bowers & Wilkins PI7
Has A Neodymium Magnet
Bowers & Wilkins PI7
✗
Sony LinkBuds S ✓
Sony LinkBuds S have neodymium magnets, when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high SPL, with the use of high magnetic flux.
