Has Active Noise Cancellation (Noise Control)
JBL Reflect Aero TWS

JBL Endurance Peak 2 ✗
Active noise cancellation uses more advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. Simply put, it's like having +1 (sound from your surrounding) and producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
The JBL Reflect Aero TWS have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to overcome background sounds.
Has Passive Noise Reduction

JBL Endurance Peak 2 ✓
The JBL Endurance Peak 2 sit well in place, creating an acoustic seal that reduces your environment sounds well as preventing the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction this means that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
JBL Reflect Aero TWS
6.8mm
JBL Endurance Peak 2 10mm
JBL Endurance Peak 2 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that makes sound in the earbuds, the unit size corellates with the sound produced by the earbuds.
JBL Reflect Aero TWS driver unit is 6.8mm in diameter,
which implies that they have a smaller driver unit than that of JBL Endurance Peak 2 by 3.2mm
, many people have a misconception 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 mean that they produce better quality sound.
Lowest Frequency
JBL Reflect Aero TWS
20Hz
JBL Endurance Peak 2 20Hz
The JBL Endurance Peak 2's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low audible frequencies and if it alters the signal on its way through.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
JBL Reflect Aero TWS
20000Hz
JBL Endurance Peak 2 20000Hz
JBL Endurance Peak 2's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio component makes high audible frequencies and if it makes any adjustments to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
JBL Reflect Aero TWS
99dB/mW
JBL Endurance Peak 2 93dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, JBL Endurance Peak 2's measurement is 93dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Reflect Aero TWS's sound pressure level measurement is 99dB/mW. How loud something is can be perceived differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
