Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Wave Buds ✓
ANC makes use of more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after generates a mirror signal to counter it. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving zero thus "diluting" the noise.
The JBL Wave Buds have ANC allowing you to listen at lower levels of volume, good for your ears as you don't have to crank up the device volume to overcome background noise.
The Sony WF 1000XM4 too have Active Noise Cancellation which makes either of the earbuds ideal for plane rides and rush hour commutes. The JBL Wave Buds and Sony WF 1000XM4 operate with different noise cancellation modes, pick the mode that you prefer for commute or that enhances your relaxation time.
Has Passive Noise Reduction

JBL Wave Buds ✓
The JBL Wave Buds stay tightly in place, this creates an acoustic covering that tones down your environment sounds and also prevents the device sound from leaking out at the same.
Both of these devices have passive noise reduction which means that they reduce ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Wave Buds 8mm
The JBL Wave Buds have a unit size of 8mm in diameter, the bigger the unit the more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Wave Buds by 2mm
, as many tend to believe 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 can generate louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JBL Wave Buds 20Hz
The JBL Wave Buds's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low frequencies that can be heard, and if it alters the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40,000Hz
JBL Wave Buds 20,000Hz
The JBL Wave Buds's highest frequency is at 20,000Hz, high-frequency response shows how well a particular audio component makes high audible frequencies and if it adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40,000Hz, this means that
Sony WF 1000XM4 can generate a clearer and crispier treble than the JBL Wave Buds
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
JBL Wave Buds 100dB/mW
SPL, is the level of pressure of sound, measured in decibels, dB, JBL Wave Buds's measurement is 100dB/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 taken differently by different persons, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
