Has Active Noise Cancellation (Noise Control)

JBL Reflect Aero TWS ✓
ANC utilises more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving 0 thus "diluting" the noise.
The Bowers & Wilkins PI7 have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to overcome background sounds.
JBL Reflect Aero TWS too have ANC making either of the devices ideal for flights and rush hour commutes. The Bowers & Wilkins PI7 and JBL Reflect Aero TWS operate with different noise cancellation modes, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.
Has Passive Noise Reduction

The Bowers & Wilkins PI7 sit tightly in place, this creates an acoustic covering that tones down your environment sounds and also prevents the device sound from leaking out .
Both JBL Reflect Aero TWS, and Bowers & Wilkins PI7 have passive noise reduction this implies that they limit ambient noise without using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL Reflect Aero TWS 6.8mm
The Bowers & Wilkins PI7 have a unit size of 9.2mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, the unit size dictates the loudness of the device.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which means that they have a smaller driver unit than that of Bowers & Wilkins PI7 by 2.4mm
, 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 can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
JBL Reflect Aero TWS 20Hz
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it alters the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that
Bowers & Wilkins PI7 produce a juicier bass than the JBL Reflect Aero TWS
Highest Frequency
Bowers & Wilkins PI7
20000Hz
JBL Reflect Aero TWS 20000Hz
The Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio component makes high recognizable frequencies and if it makes any changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JBL Reflect Aero TWS 99dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Reflect Aero TWS's measurement is 99dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
