Has Active Noise Cancellation (Noise Control)

Sony WF C500 ✗
Active noise cancellation makes use of more advanced kind of tech to reduce ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 thus "diluting" the noise.
Bowers & Wilkins PI7 have ANC allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction
Bowers & Wilkins PI7
✓
Sony WF C500 ✓
Bowers & Wilkins PI7 stay well in place, creating an acoustic seal that tones down background noise well as preventing the device music from leaking out .
Both of these devices have passive noise reduction which means that they tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
Sony WF C500 5.8mm
The 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 makes sound in the device, its size corellates with the sound produced by the device.
Sony WF C500 driver unit is 5.8mm in diameter,
which means that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 3.4mm
, 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 are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
Sony WF C500 20Hz
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well an audio component generates low recognizable frequencies and if it makes any changes to the signal while at it.
Sony WF C500's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 can make sound with a juicier bass than the Sony WF C500
Highest Frequency
Bowers & Wilkins PI7
20000Hz
Sony WF C500 20000Hz
Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response indicates how well an audio device generates high human frequencies and if it adjustments to the signal on its way through.
Sony WF C500's highest frequency is at 20000Hz, this implies that
both devices generate equal treble
Has A Neodymium Magnet
Bowers & Wilkins PI7
✗
Sony WF C500 ✓
The Sony WF C500 have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high SPL, with the use of high magnetic flux.
