Has Active Noise Cancellation (Noise Control)

Sony LinkBuds S ✓
ANC uses advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (noise) and adding -1 (counter sound by the device) to make zero resulting in a reduced level of noise.
Bowers & Wilkins PI7 have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.
Sony LinkBuds S too have Active Noise Cancellation which makes both devices ideal for plane rides and morning commutes. The Bowers & Wilkins PI7 and Sony LinkBuds S operate with different noise cancellation modes, pick the noise cancellation type that suits your commute or that suites your chill time.
Has Passive Noise Reduction

Sony LinkBuds S ✓
Bowers & Wilkins PI7 stay well in place, this creates an acoustic seal that reduces your environment noise and also prevents the device sound from leaking out .
Both of these devices have passive noise reduction which means that they limit ambient noise instead of actively using technology 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, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the device.
Sony LinkBuds S driver unit is 5mm in diameter,
which implies that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 4.2mm
, 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 yeah, larger drivers are capable of generating louder sound, but this does not indicate that they deliver 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 an audio component produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Sony LinkBuds S's lowest frequency is at 20Hz, this means that
Bowers & Wilkins PI7 make sound with a juicier bass than the Sony LinkBuds S
Highest Frequency
Bowers & Wilkins PI7
20,000hz
Sony LinkBuds S 40,000hz
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device generates high audible frequencies and if it makes any changes to the signal while at it.
Sony LinkBuds S's highest frequency is at 40,000Hz, 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 ✓
The Sony LinkBuds S have neodymium magnets, if 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 sound pressure level, with the use of high magnetic flux.
