Has Active Noise Cancellation (Noise Control)
JBL Live Free 2
✓
JLab Go Air ✗
ANC uses more advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern of incoming noise and inverts the soundwaves to counter it. Simply put, it's like taking +1 (noise) and adding -1 (inverted noise) giving zero thus "diluting" the noise.
JBL Live Free 2 have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to overcome background sounds.
Has Passive Noise Reduction

JLab Go Air ✓
The JLab Go Air stay tightly in place, creating a sound seal that tones down your environment noise and also prevents the earbuds sound from leaking out .
Both JBL Live Free 2, and JLab Go Air have passive noise reduction which means that they reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
JBL Live Free 2
11mm
JLab Go Air 8mm
The JLab Go Air driver unit is 8mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is the component that makes sound in the earbuds, its size corellates with 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 by 3mm
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
JBL Live Free 2
20Hz
JLab Go Air 20Hz
The JLab Go Air's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates 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
JBL Live Free 2
20000Hz
JLab Go Air 20000Hz
The JLab Go Air's highest frequency is at 20000Hz, high-frequency response tells how well a particular audio device generates high human frequencies and if it makes any changes to the signal on its way through.
JBL Live Free 2's highest frequency is at 20000Hz, this means that
both devices can 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, measured 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. How loud a device is can be perceived differently by separate people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet

JLab Go Air ✓
JLab Go Air have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high SPL, with the use of high magnetic flux.
