ANC utilises more advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (noise) then adding -1 (inverted noise) giving zero hence "diluting" the noise.
The JBL Reflect Aero TWS have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the earbuds volume to outcompete background sounds.
The JBL Live Free 2 too have ANC making both earbuds ideal for flights and morning travels. The JBL Reflect Aero TWS and JBL Live Free 2 operate with different noise cancellation modes, pick the noise cancellation type that you prefer for travel or that enhances your chill time.

Driver Unit Size
JBL Reflect Aero TWS
6.8mm
JBL Live Free 2 11mm
The JBL Reflect Aero TWS have a unit size of 6.8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is the component that makes sound in the earbuds, its size corellates with the sound made by the earbuds.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of JBL Reflect Aero TWS by 4.2mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
JBL Reflect Aero TWS
20Hz
JBL Live Free 2 20Hz
The JBL Reflect Aero TWS's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it alters the signal on its way through.
JBL Live Free 2's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Highest Frequency
JBL Reflect Aero TWS
20000Hz
JBL Live Free 2 20000Hz
The JBL Reflect Aero TWS's highest frequency is at 20000Hz, high-frequency response indicates how well a particular audio device produces high human frequencies and if it makes any changes to the signal on its way through.
JBL Live Free 2's highest frequency is at 20000Hz, this implies that
both devices can generate equal treble
Sound Pressure Level
JBL Reflect Aero TWS
99dB/mW
JBL Live Free 2 102dB/mW
The sound pressure level, is the pressure level of sound, 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 Free 2's sound pressure level measurement is 102dB/mW. How loud something is can be perceived differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
