ANC makes use of more advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The JBL Reflect Aero TWS have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to outcompete background sounds.
The JBL Live Free 2 too have ANC making either of the devices ideal for flights and morning commutes. Each operate with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that suites your chill time.

Driver Unit Size
JBL Reflect Aero TWS
6.8mm
JBL Live Free 2 11mm
JBL Reflect Aero TWS driver unit is 6.8mm in diameter, bigger drivers are more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the device, the unit size determines the sound produced by the device.
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 find it difficult to produce high frequencies so yes, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JBL Reflect Aero TWS
20Hz
JBL Live Free 2 20Hz
JBL Reflect Aero TWS's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
JBL Live Free 2's lowest frequency is at 20Hz, this means that
both devices make sound with 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 shows how well an audio device generates high audible frequencies and if it adjustments to the signal on its way through.
JBL Live Free 2's highest frequency is at 20000Hz, this means that
both devices produce equal treble
Sound Pressure Level
JBL Reflect Aero TWS
99dB/mW
JBL Live Free 2 102dB/mW
SPL, 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 a device is can be considered differently by different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
