Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Wave Buds ✓
ANC utilises more advanced technology to actively cancel noise. ANC works when, it studies 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 (noise) and producing -1 (counter sound by the device) giving 0 hence "diluting" the noise.
The JBL Wave Buds have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't need to crank up the earbuds volume to overcome background noise.
Sony WF 1000XM4 too have ANC making either of the devices ideal for flights and rush hour commutes. The JBL Wave Buds and Sony WF 1000XM4 operate with different noise cancellation settings, pick the noise cancellation type that suits your commute or that suites your relaxation time.
Has Passive Noise Reduction

JBL Wave Buds ✓
JBL Wave Buds sit well in place, creating an acoustic covering that tones down background sounds well as preventing the earbuds sound from leaking out .
Both of these devices have passive noise reduction which means that they reduce ambient noise without using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Wave Buds 8mm
JBL Wave Buds 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 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
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yes, larger drivers can generate louder sound, but this does not imply 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 an audio device generates low audible frequencies and if it makes any changes to the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means 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 an audio device produces high recognizable frequencies and if it makes any 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 pressure level 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. How loud a device is can be perceived differently by separate persons, so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
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 using less power to do so. They can help generate music at quite a high sound pressure level, using high magnetic flux.
