Active noise cancellation utilises advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero resulting in a reduced level of noise.
The JBL Tune Flex have ANC enabling you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the device volume to overcome background sounds.

which means that they have a smaller driver unit than that of JBL Tune Flex by 6mm
, 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 yeah, larger drivers can generate louder sound, but this does not indicate that they produce better quality sound. JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices make sound with equal bass
JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well a particular audio device produces high recognizable frequencies and if it changes to the signal while at it. Sony WF 1000XM4's highest frequency is at 40,000Hz, this means that
Sony WF 1000XM4 can generate a clearer and crispier treble than the JBL Tune Flex
The sound pressure level, 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.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. The sound pressure level, a device is can be perceived differently by separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms. JBL Tune Flex's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
