Has Active Noise Cancellation (Noise Control)
JBL Tune Flex

JBL Reflect Aero TWS ✓
ANC utilises advanced kind of tech to reduce unwanted ambient sounds. How it works, it listens to the sound pattern outside and inside the earbud and generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 which results in a reduced level of noise.
JBL Tune Flex have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the earbuds volume to overcome background sounds.
JBL Reflect Aero TWS too have ANC making both devices ideal for plane rides and morning commutes. The JBL Tune Flex and JBL Reflect Aero TWS work with different noise cancellation settings, pick the mode that you prefer for travel or that enhances your chill time.

Driver Unit Size
JBL Tune Flex
12mm
JBL Reflect Aero TWS 6.8mm
The JBL Tune Flex have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that produces sound in the earbuds, its size dictates 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 JBL Tune Flex by 5.2mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers can generate louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JBL Tune Flex
20Hz
JBL Reflect Aero TWS 20Hz
JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low audible frequencies and if it alters the signal while at it.
JBL Reflect Aero TWS's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
Highest Frequency
JBL Tune Flex
20,000Hz
JBL Reflect Aero TWS 20,000Hz
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device produces high recognizable frequencies and if it adjustments to the signal on its way through.
JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this means that
both devices can produce equal treble
Sound Pressure Level
JBL Tune Flex
108dB/mW
JBL Reflect Aero TWS 99dB/mW
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, JBL Tune Flex's measurement is 108dB/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 considered differently by separate people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
