JBL Live Free 2 ✓
Active noise cancellation makes use of advanced technology to reduce 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. In simple terms, it's like taking +1 (noise) then adding -1 (counter sound by the device) giving zero thus "diluting" the noise.
The JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to outcompete background noise.
The Sennheiser Momentum True Wireless 3 too have Active Noise Cancellation making both devices ideal for plane rides and rush hour commutes. The JBL Live Free 2 and Sennheiser Momentum True Wireless 3 operate with different noise cancellation types, pick the noise cancellation type that suits your commute or that suites your chill time.

Sennheiser Momentum True Wireless 3
21000Hz
JBL Live Free 2 20000Hz
The JBL Live Free 2's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio device generates high audible frequencies and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a clearer and crispier treble than the JBL Live Free 2
Sound Pressure Level
Sennheiser Momentum True Wireless 3
107dB/mW
JBL Live Free 2 102dB/mW
SPL, is the level of pressure of sound, in decibels, dB, JBL Live Free 2's measurement is 102dB/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 different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
