Has Active Noise Cancellation (Noise Control)
JBL Live Free 2
✓
JLab Go Air ✗
ANC makes use of more advanced technology to actively cancel noise. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (noise) then adding -1 (counter sound by the device) to make zero hence "diluting" the noise.
The JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.
Has Passive Noise Reduction

JLab Go Air ✓
The JLab Go Air sit tightly in place, this creates an acoustic seal that tones down your environment noise and also prevents the earbuds voice audio from leaking out at the same.
Both JBL Live Free 2, and JLab Go Air have passive noise reduction which means that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
JBL Live Free 2
11mm
JLab Go Air 8mm
The JLab Go Air have a unit size of 8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the loudness of the earbuds.
JBL Live Free 2 driver unit is 11mm in diameter,
making them have a larger driver unit than that of JLab Go Air by 3mm
, 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 are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
JBL Live Free 2
20hz
JLab Go Air 20hz
JLab Go Air's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it makes any changes to 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
JBL Live Free 2
20,000hz
JLab Go Air 20,000hz
The JLab Go Air's highest frequency is at 20,000Hz, high-frequency response tells how well an audio device produces high recognizable frequencies and if it makes any adjustments to the signal while at it.
JBL Live Free 2's highest frequency is at 20,000Hz, this implies that
both devices generate equal treble
Sound Pressure Level
JBL Live Free 2
102db/mw
JLab Go Air 103db/mw
The sound pressure level, is the level of pressure of sound, in decibels, dB, JLab Go Air'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. The sound pressure level, something is can be taken differently by different people, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
JBL Live Free 2

JLab Go Air ✓
The JLab Go Air have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high sound pressure level, using high magnetic flux.
