Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7
✓
JBL Reflect Aero TWS ✓
ANC utilises more advanced kind of tech to actively counter noise. How it works, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) then producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background sounds.
The JBL Reflect Aero TWS too have Active Noise Cancellation which makes both devices ideal for flights and rush hour travels. The Bowers & Wilkins PI7 and JBL Reflect Aero TWS work with different noise cancellation settings, pick the mode that you prefer for commute or that suites your chill time.
Has Passive Noise Reduction

The Bowers & Wilkins PI7 sit well in place, this creates a sound covering that reduces background noise and also prevents the earbuds music from leaking out at the same.
Both JBL Reflect Aero TWS, and Bowers & Wilkins PI7 have passive noise reduction which implies that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
JBL Reflect Aero TWS 6.8mm
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 device, the unit size corellates with 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 are capable of generating louder sound, but this does not indicate that they deliver 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 measures if and how well a particular audio device generates low frequencies that can be heard, and if it alters the signal on its way through.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that
Bowers & Wilkins PI7 make sound with 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 device produces high recognizable frequencies and if it changes to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
Bowers & Wilkins PI7
✗
JBL Reflect Aero TWS 99dB/mW
The sound pressure level, is the level of pressure 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.
