Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Wave Buds ✗
Active noise cancellation uses advanced kind of tech to actively cancel noise. ANC works when, it listens to the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) giving zero thus "diluting" the noise.
Sony WF 1000XM4 have Active Noise Cancellation enabling you to listen at lower volume levels, good for your ears as you don't have to crank up the device volume to outcompete background sounds.
Has Passive Noise Reduction

JBL Wave Buds ✓
JBL Wave Buds sit tightly in place, creating a sound covering that reduces your environment sounds and also prevents the device music from leaking out at the same.
Both of these devices have passive noise reduction which implies that both reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Wave Buds 8mm
The JBL Wave Buds driver unit is 8mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is the component that produces sound in the earbuds, its size corellates with 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 JBL Wave Buds by 2mm
, a common assumption 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 indicate that they deliver 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 inidcates how well a particular audio component generates low frequencies that can be heard, and if it makes any changes to 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
40000Hz
JBL Wave Buds 20000Hz
The JBL Wave Buds'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 makes any adjustments 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 JBL Wave Buds
Sound Pressure Level
Sony WF 1000XM4
✗
JBL Wave Buds 100dB/mW
The sound pressure level, 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.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
JBL Wave Buds ✗
The Sony WF 1000XM4 have neodymium magnets, when 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.
