Has Active Noise Cancellation (Noise Control)
JBL Live Pro 2
✓
Bowers & Wilkins PI7 ✓
Active noise cancellation makes use of more advanced technology to actively cancel noise. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make zero therefore "diluting" the noise.
Bowers & Wilkins PI7 have ANC allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise.
JBL Live Pro 2 too have ANC which makes either of the devices ideal for flights and rush hour travels. Each operate with different noise cancellation settings, pick the mode that suits your travel or that enhances your relaxation time.
Has Passive Noise Reduction
JBL Live Pro 2
✓
Bowers & Wilkins PI7 ✓
Bowers & Wilkins PI7 sit well in place, creating a sound seal that reduces background noise well as preventing the device music from leaking out at the same.
Both JBL Live Pro 2, and Bowers & Wilkins PI7 have passive noise reduction which implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
JBL Live Pro 2
11mm
Bowers & Wilkins PI7 9.2mm
The 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 basically a mini speaker that produces sound in the earbuds, the unit size corellates with the loudness of the device.
JBL Live Pro 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Bowers & Wilkins PI7 by 1.8mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JBL Live Pro 2
20hz
Bowers & Wilkins PI7 10hz
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well a particular audio device produces low recognizable frequencies and if it alters the signal while at it.
JBL Live Pro 2's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 can produce a juicier bass than the JBL Live Pro 2
Highest Frequency
JBL Live Pro 2
20,000hz
Bowers & Wilkins PI7 20,000hz
The Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio device produces high audible frequencies and if it makes any changes to the signal while at it.
JBL Live Pro 2's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
Sound Pressure Level
JBL Live Pro 2
93db/mw
Bowers & Wilkins PI7 ✗
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Live Pro 2's measurement is 93dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
