ANC uses advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) and producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
Sony WF 1000XM3 have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background noise.
The Bowers & Wilkins PI7 too have Active Noise Cancellation making either of the earbuds ideal for flights and rush hour travels. The Sony WF 1000XM3 and Bowers & Wilkins PI7 work with different noise cancellation modes, pick the noise cancellation type that you prefer for commute or that suites your relaxation time.

Driver Unit Size
Sony WF 1000XM3
6mm
Bowers & Wilkins PI7 9.2mm
Sony WF 1000XM3 have a unit size of 6mm 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 sound produced by the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
making them have a larger driver unit than that of Sony WF 1000XM3 by 3.2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM3
20Hz
Bowers & Wilkins PI7 10Hz
Sony WF 1000XM3's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low recognizable frequencies and if it alters 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 Sony WF 1000XM3
Highest Frequency
Sony WF 1000XM3
20000Hz
Bowers & Wilkins PI7 20000Hz
The Sony WF 1000XM3's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio device makes high audible frequencies and if it makes any adjustments to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
Has A Neodymium Magnet

Bowers & Wilkins PI7 ✗
Sony WF 1000XM3 have neodymium magnets, if used in earbuds 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.
