Active noise cancellation uses more advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and after generates a mirror signal to cancel it out. In simple terms, 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.
The JBL Reflect Aero TWS have ANC enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to outcompete background noise.
The Sennheiser Momentum True Wireless 3 too have ANC making both devices ideal for plane rides and rush hour commutes. Each operate with different noise cancellation modes, pick the setting that you prefer for commute or that enhances your chill time.
Has Passive Noise Reduction

JBL Reflect Aero TWS ✓
JBL Reflect Aero TWS stay well in place, creating a sound covering that tones down background sounds and also prevents the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction this means that both limit ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sennheiser Momentum True Wireless 3
7mm
JBL Reflect Aero TWS 6.8mm
JBL Reflect Aero TWS have a unit size of 6.8mm 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, the unit size determines the sound made by the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
making them have a larger driver unit than that of JBL Reflect Aero TWS by 0.2mm
, many people have a misconception 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 imply that they produce better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 3
5Hz
JBL Reflect Aero TWS 20Hz
JBL Reflect Aero TWS's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low recognizable frequencies and if it alters the signal on its way through.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 make sound with a juicier bass than the JBL Reflect Aero TWS
Highest Frequency
Sennheiser Momentum True Wireless 3
21000Hz
JBL Reflect Aero TWS 20000Hz
JBL Reflect Aero TWS's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio component produces 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 21000Hz, this means that
Sennheiser Momentum True Wireless 3 can generate a clearer and crispier treble than the JBL Reflect Aero TWS
Sound Pressure Level
Sennheiser Momentum True Wireless 3
107dB/mW
JBL Reflect Aero TWS 99dB/mW
The sound pressure level, is the pressure level of sound, measured in decibels, dB, JBL Reflect Aero TWS's measurement is 99dB/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. The sound pressure level, a device is can be taken differently by different persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
