Active noise cancellation uses advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then adding -1 (inverted noise) giving 0 which results in a reduced level of noise.
JBL Tune Flex have Active Noise Cancellation enabling you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise. The JBL Reflect Aero TWS too have Active Noise Cancellation which makes both earbuds ideal for plane rides and rush hour travels.

JBL Tune Flex driver unit is 12mm in diameter, bigger drivers are more powerful, and can produce better bass. The driver unit is basically a mini speaker that produces sound in the earbuds, its size dictates 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 Tune Flex by 5.2mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so it's true that, larger drivers can generate louder sound, but this does not imply that they deliver better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device generates 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
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response shows how well an audio device generates high recognizable frequencies and if it adjustments to the signal while at it. JBL Reflect Aero TWS's highest frequency is at 20,000Hz, this implies that
both devices can generate equal treble
SPL, 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 taken differently by different people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms. The JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
