Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JLab Go Air ✗
ANC makes use of more advanced technology to actively counter noise. ANC works when, it studies the sound pattern of incoming noise and then inverts the soundwaves to counter it. In simple terms, it's like taking +1 (noise) and producing -1 (counter sound by the device) to make zero therefore "diluting" the noise.
Sony WF 1000XM4 have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the device volume to outcompete background sounds.
Has Passive Noise Reduction

JLab Go Air ✓
JLab Go Air stay well in place, this creates a sound seal that tones down your environment sounds well as preventing the earbuds music from leaking out .
Both of these devices have passive noise reduction this implies that they limit ambient noise without using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JLab Go Air 8mm
The JLab Go Air have a unit size of 8mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the earbuds, its size corellates with the sound produced by the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of JLab Go Air by 2mm
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JLab Go Air 20Hz
JLab Go Air's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
JLab Go Air 20000Hz
JLab Go Air's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio component generates high human frequencies and if it changes to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 produce a clearer and crispier treble than the JLab Go Air
Sound Pressure Level
Sony WF 1000XM4
✗
JLab Go Air 103dB/mW
SPL, is the pressure level 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.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
JLab Go Air ✓
The 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, using high magnetic flux.
Sony WF 1000XM4 have it too, devices with these magnets are lighter and more powerful than those which use ferrite magnets. It is also known that they have more bass and clearer high notes.
