Active noise cancellation utilises more advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) giving zero which results in a reduced level of noise.
JBL Tune Flex have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to outcompete background noise.

Bose QuietComfort 2 driver unit is 9.3mm in diameter,
which means that they have a smaller driver unit than that of JBL Tune Flex by 2.7mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers can generate louder sound, but this does not mean that they produce better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces low audible frequencies and if it makes any changes to the signal on its way through.
Bose QuietComfort 2's lowest frequency is at 20Hz, this implies that
both devices can produce equal bass
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component produces high human frequencies and if it changes to the signal on its way through. Bose QuietComfort 2's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
SPL, is the pressure level 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.
