Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JEET W1S ✗
ANC uses advanced technology to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and after inverts the soundwaves to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero therefore "diluting" the noise.
The Sony WF 1000XM4 have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction

✓
JEET W1S ✓
The JEET W1S stay tightly in place, creating an acoustic covering that tones down background sounds and also prevents the earbuds music from leaking out .
Both Sony WF 1000XM4, and JEET W1S have passive noise reduction which implies that they tone down ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JEET W1S 11mm
The JEET W1S have a unit size of 11mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is the component that makes sound in the device, the unit size determines the sound produced by the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of JEET W1S by 5mm
, 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 imply that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JEET W1S 20Hz
JEET W1S's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device generates low recognizable frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
JEET W1S 20000Hz
The JEET W1S's highest frequency is at 20000Hz, high-frequency response indicates how well an audio device makes high human frequencies and if it adjustments to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 can produce a clearer and crispier treble than the JEET W1S
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
JEET W1S 93dB/mW
SPL, is the level of pressure of sound, measured in decibels, dB, JEET W1S's measurement is 93dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Sony WF 1000XM4's sound pressure level measurement is 105dB/mW. The sound pressure level, something is can be considered differently by separate persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
JEET W1S ✗
Sony WF 1000XM4 have neodymium magnets, when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high SPL, with the use of high magnetic flux.
