Has Active Noise Cancellation (Noise Control)

ANC uses advanced technology to reduce unwanted ambient sounds. ANC works when, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving zero thus "diluting" the noise.
Bowers & Wilkins PI7 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background sounds.
The JBL Tour Pro 2 too have ANC making either of the devices ideal for flights and rush hour travels. The Bowers & Wilkins PI7 and JBL Tour Pro 2 work with different noise cancellation types, pick the setting that suits your travel or that suites your chill time.
Has Passive Noise Reduction

JBL Tour Pro 2 ✓
The Bowers & Wilkins PI7 sit tightly in place, this creates an acoustic seal that reduces your environment sounds while preventing the device sound from leaking out at the same.
Both of these devices have passive noise reduction this implies that both reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL Tour Pro 2 10mm
Bowers & Wilkins PI7 have a unit size of 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 device, its size corellates with the sound made by the device.
JBL Tour Pro 2 driver unit is 10mm in diameter,
making them have a larger driver unit than that of Bowers & Wilkins PI7 by 0.8mm
, a common assumption 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 can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
JBL Tour Pro 2 20Hz
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Tour Pro 2's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 make sound with a juicier bass than the JBL Tour Pro 2
Highest Frequency
Bowers & Wilkins PI7
20,000Hz
JBL Tour Pro 2 20,000Hz
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response tells how well an audio device generates high recognizable frequencies and if it makes any changes to the signal on its way through.
JBL Tour Pro 2's highest frequency is at 20,000Hz, this implies that
both devices produce equal treble
