Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Tour Pro 2 ✓
Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. ANC works when, it listens to the sound pattern outside and inside the earbud and then generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 hence "diluting" the noise.
JBL Tour Pro 2 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue as you don't need to crank up the device volume to outcompete background noise.
Sony WF 1000XM4 too have ANC which makes both devices ideal for flights and rush hour travels. Each work with different noise cancellation settings, pick the mode that suits your travel or that suites your chill time.
Has Passive Noise Reduction

✓
JBL Tour Pro 2 ✓
JBL Tour Pro 2 stay tightly in place, this creates a sound seal that tones down background noise while preventing the device sound from leaking out at the same.
Both of these devices have passive noise reduction this implies that they tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Tour Pro 2 10mm
The JBL Tour Pro 2 driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is the component that makes sound in the earbuds, the unit size corellates with the sound produced by the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tour Pro 2 by 4mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers can generate louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JBL Tour Pro 2 20Hz
The JBL Tour Pro 2's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low frequencies that can be heard, and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
JBL Tour Pro 2 20000Hz
The JBL Tour Pro 2's highest frequency is at 20000Hz, high-frequency response shows how well an audio component makes high recognizable frequencies and if it makes any changes to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 can produce a clearer and crispier treble than the JBL Tour Pro 2
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
JBL Tour Pro 2 ✗
SPL, is the pressure level of sound, measured in decibels, dB, Sony WF 1000XM4's measurement is 105dB/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 Tour Pro 2 ✗
The Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, using high magnetic flux.
