Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7
✓
JBL Wave Beam ✓
Active noise cancellation uses more advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) then producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The JBL Wave Beam have ANC allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to outcompete background sounds.
The Bowers & Wilkins PI7 too have ANC which makes both devices ideal for plane rides and rush hour travels. The JBL Wave Beam and Bowers & Wilkins PI7 work with different noise cancellation types, pick the mode that you prefer for travel or that enhances your chill time.
Has Passive Noise Reduction

JBL Wave Beam ✓
JBL Wave Beam sit tightly in place, this creates a sound covering that tones down background noise and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction which means that both tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL Wave Beam 8mm
JBL Wave Beam have a unit size of 8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is the component that produces sound in the device, its size dictates 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 JBL Wave Beam 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 it's true that, 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 Wave Beam 20Hz
The JBL Wave Beam's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low recognizable frequencies 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 make sound with a juicier bass than the JBL Wave Beam
Highest Frequency
Bowers & Wilkins PI7
20,000Hz
JBL Wave Beam 20,000Hz
The JBL Wave Beam's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device produces high human frequencies and if it makes any adjustments to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices can generate equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JBL Wave Beam 100dB/mW
SPL, is the level of pressure of sound, in decibels, dB, JBL Wave Beam's measurement is 100dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
