Has Active Noise Cancellation (Noise Control)

JBL Reflect Aero TWS ✓
ANC makes use of more advanced kind of tech to reduce ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make zero hence "diluting" the noise.
JBL Reflect Aero TWS have ANC allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the earbuds volume to overcome background sounds.
The JBL Live Pro 2 too have ANC making either of the devices ideal for plane rides and rush hour commutes. Each work with different noise cancellation settings, pick the noise cancellation type that suits your commute or that suites your relaxation time.

JBL Reflect Aero TWS stay tightly in place, this creates an acoustic covering that tones down your environment noise and also prevents the earbuds music from leaking out .
Both of these devices have passive noise reduction this implies that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
JBL Live Pro 2
11mm
JBL Reflect Aero TWS 6.8mm
JBL Reflect Aero TWS have a unit size of 6.8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the device, its size corellates with the loudness of the device.
JBL Live Pro 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of JBL Reflect Aero TWS by 4.2mm
, 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 deliver better quality sound.
Lowest Frequency
JBL Live Pro 2
20Hz
JBL Reflect Aero TWS 20Hz
The JBL Reflect Aero TWS's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Live Pro 2's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
JBL Live Pro 2
20000Hz
JBL Reflect Aero TWS 20000Hz
The JBL Reflect Aero TWS's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component produces high audible frequencies and if it adjustments to the signal on its way through.
JBL Live Pro 2's highest frequency is at 20000Hz, this implies that
both devices produce equal treble
Sound Pressure Level
JBL Live Pro 2
93dB/mW
JBL Reflect Aero TWS 99dB/mW
SPL, 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.
JBL Live Pro 2's sound pressure level measurement is 93dB/mW. The sound pressure level, a device is can be considered differently by separate people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
