ANC makes use of advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and inverts the soundwaves to counter it. In simple terms, it's like having +1 (noise) and producing -1 (inverted noise) giving zero which results in a reduced level of noise.
The JBL Tune Flex have ANC allowing you to listen at lower levels of volume, good for your ears since you don't need to crank up the device volume to overcome background sounds.
The Sennheiser Momentum True Wireless 3 too have ANC making both earbuds ideal for flights and morning commutes. Each operate with different noise cancellation modes, pick the noise cancellation type that you prefer for travel or that suites your relaxation time.

JBL Tune Flex sit tightly in place, this creates an acoustic seal that reduces background noise and also prevents the earbuds music from leaking out at the same.
Both of these devices have passive noise reduction this implies that both reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
JBL Tune Flex
12mm
Sennheiser Momentum True Wireless 3 7mm
The JBL Tune Flex have a unit size of 12mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune Flex by 5mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JBL Tune Flex
20Hz
Sennheiser Momentum True Wireless 3 5Hz
JBL Tune Flex's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low recognizable frequencies and if it makes any changes to the signal while at it.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 produce a juicier bass than the JBL Tune Flex
Highest Frequency
JBL Tune Flex
20,000Hz
Sennheiser Momentum True Wireless 3 21,000Hz
The JBL Tune Flex's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio component makes high human frequencies and if it makes any adjustments to the signal while at it.
Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a clearer and crispier treble than the JBL Tune Flex
Sound Pressure Level
JBL Tune Flex
108dB/mW
Sennheiser Momentum True Wireless 3 107dB/mW
SPL, is the pressure level of sound, 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.
Sennheiser Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. How loud something is can be considered differently by separate persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
