Has Active Noise Cancellation (Noise Control)

JBL LIVE 300 ✗
Active noise cancellation utilises more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) to make zero therefore "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.

Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL LIVE 300 5.8mm
The JBL LIVE 300 driver unit is 5.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the earbuds, the unit size determines the sound made by the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
making them have a larger driver unit than that of JBL LIVE 300 by 3.4mm
, 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 yes, 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 LIVE 300 20Hz
JBL LIVE 300's lowest frequency is at 20Hz, low-frequency response inidcates how well an 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 make sound with a juicier bass than the JBL LIVE 300
Highest Frequency
Bowers & Wilkins PI7
20000Hz
JBL LIVE 300 20000Hz
The JBL LIVE 300's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio device makes high human frequencies and if it makes any changes to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20000Hz, this means that
both devices produce equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JBL LIVE 300 95dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL LIVE 300's measurement is 95dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
