Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7
✓
JLab Go Air ✗
ANC utilises more advanced kind of tech to actively counter noise. ANC works when, it listens to the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving 0 thus "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue as 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 sit tightly in place, this creates a sound seal that reduces your environment sounds and also prevents the earbuds music from leaking out at the same.
Both Bowers & Wilkins PI7, and JLab Go Air have passive noise reduction which implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JLab Go Air 8mm
The JLab Go Air driver unit is 8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that produces sound in the device, its size determines the loudness of the earbuds.
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
, a common assumption 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 can generate 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 measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal on its way through.
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
20000Hz
JLab Go Air 20000Hz
JLab Go Air's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component generates high audible frequencies and if it changes to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JLab Go Air 103dB/mW
The sound pressure level, is the level of pressure of sound, 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.
Has A Neodymium Magnet
Bowers & Wilkins PI7
✗
JLab Go Air ✓
The JLab Go Air have neodymium magnets, when 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 sound pressure level, using high magnetic flux.
