Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7

JLab Go Air ✗
ANC utilises advanced technology to reduce unwanted ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving 0 hence "diluting" the noise.
The Bowers & Wilkins PI7 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.
Has Passive Noise Reduction

JLab Go Air ✓
The JLab Go Air stay tightly in place, creating an acoustic covering that reduces your environment sounds well as preventing the earbuds sound from leaking out .
Both Bowers & Wilkins PI7, and JLab Go Air 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
JLab Go Air 8mm
The JLab Go Air have a unit size of 8mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the device, the unit size corellates with the loudness of the device.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
making them have a larger driver unit than that of JLab Go Air by 1.2mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
JLab Go Air 20Hz
The JLab Go Air's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this means that
Bowers & Wilkins PI7 can produce a juicier bass than the JLab Go Air
Highest Frequency
Bowers & Wilkins PI7
20,000Hz
JLab Go Air 20,000Hz
The JLab Go Air's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component makes high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this means that
both devices generate equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JLab Go Air 103dB/mW
SPL, is the level of pressure of sound, measured in decibels, dB, JLab Go Air's measurement is 103dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
