Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving zero therefore "diluting" the noise.
JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears as you don't need to crank up the device volume to outcompete background sounds.

Driver Unit Size
JLab Go Air Pop
6mm
JBL Live Free 2 11mm
The JLab Go Air Pop driver unit is 6mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the earbuds, the unit size determines the loudness of the device.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of JLab Go Air Pop by 5mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
JLab Go Air Pop
20hz
JBL Live Free 2 20hz
The JLab Go Air Pop's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio component produces low frequencies that can be heard, and if it alters the signal while at it.
JBL Live Free 2's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
JLab Go Air Pop
20,000hz
JBL Live Free 2 20,000hz
The JLab Go Air Pop's highest frequency is at 20,000Hz, high-frequency response shows how well an audio component produces high human frequencies and if it changes to the signal while at it.
JBL Live Free 2's highest frequency is at 20,000Hz, this implies that
both devices can produce equal treble
Sound Pressure Level
JLab Go Air Pop
103db/mw
JBL Live Free 2 102db/mw
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, JLab Go Air Pop's measurement is 103dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
JBL Live Free 2's sound pressure level measurement is 102dB/mW. How loud something is can be considered differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
