Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7
✓
JBL Tour Pro 2 ✓
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and producing -1 (counter sound by the device) to make zero hence "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to outcompete background noise.
The JBL Tour Pro 2 too have Active Noise Cancellation making both devices ideal for plane rides and rush hour commutes. Each work with different noise cancellation modes, pick the noise cancellation type that you prefer for travel or that enhances your relaxation time.

JBL Tour Pro 2 ✓
Bowers & Wilkins PI7 stay well in place, creating an acoustic seal that reduces your environment noise and also prevents the device music from leaking out .
Both JBL Tour Pro 2, and Bowers & Wilkins PI7 have passive noise reduction this means that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL Tour Pro 2 10mm
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 produces sound in the earbuds, its size dictates the loudness of 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
, as many tend to believe 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 indicate that they deliver better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
JBL Tour Pro 2 20Hz
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 alters the signal on its way through.
JBL Tour Pro 2's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 can produce a juicier bass than the JBL Tour Pro 2
Highest Frequency
Bowers & Wilkins PI7
20000Hz
JBL Tour Pro 2 20000Hz
Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device produces high audible frequencies and if it adjustments to the signal while at it.
JBL Tour Pro 2's highest frequency is at 20000Hz, this implies that
both devices can produce equal treble
