✓
JBL Live Pro 2 ✓
Active noise cancellation utilises advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) and adding -1 (counter sound by the device) to make zero thus "diluting" the noise.
The Sennheiser Momentum True Wireless 4 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 device volume to overcome background noise.
JBL Live Pro 2 too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour commutes. The Sennheiser Momentum True Wireless 4 and JBL Live Pro 2 operate with different noise cancellation types, pick the noise cancellation type that you prefer for commute or that enhances your relaxation time.

Driver Unit Size
Sennheiser Momentum True Wireless 4
7mm
JBL Live Pro 2 11mm
Sennheiser Momentum True Wireless 4 driver unit is 7mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with the loudness of the device.
JBL Live Pro 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of Sennheiser Momentum True Wireless 4 by 4mm
, 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 it's true that, larger drivers can generate louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 4
5Hz
JBL Live Pro 2 20Hz
The Sennheiser Momentum True Wireless 4's lowest frequency is at 5Hz, low-frequency response measures if and how well an audio device produces low recognizable frequencies and if it alters the signal on its way through.
JBL Live Pro 2's lowest frequency is at 20Hz, this means that
Sennheiser Momentum True Wireless 4 make sound with a juicier bass than the JBL Live Pro 2
Highest Frequency
Sennheiser Momentum True Wireless 4
21,000Hz
JBL Live Pro 2 20,000Hz
The Sennheiser Momentum True Wireless 4's highest frequency is at 21,000Hz, high-frequency response indicates how well a particular audio component produces high human frequencies and if it adjustments to the signal while at it.
JBL Live Pro 2's highest frequency is at 20,000Hz, this means that
Sennheiser Momentum True Wireless 4 generate a clearer and crispier treble than the JBL Live Pro 2
Sound Pressure Level
Sennheiser Momentum True Wireless 4
107dB/mW
JBL Live Pro 2 93dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, Sennheiser Momentum True Wireless 4's measurement is 107dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Live Pro 2's sound pressure level measurement is 93dB/mW. The sound pressure level, something is can be taken differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
