Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Endurance Peak 2 ✗
Active noise cancellation uses advanced technology to reduce ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 which results in a reduced level of noise.
The Sony WF 1000XM4 have ANC allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the device volume to outcompete background noise.
Has Passive Noise Reduction

✓
JBL Endurance Peak 2 ✓
JBL Endurance Peak 2 sit well in place, creating a sound covering that reduces background noise and also prevents the earbuds sound from leaking out at the same.
Both of these devices have passive noise reduction which means that they limit ambient noise instead of actively using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Endurance Peak 2 10mm
The JBL Endurance Peak 2 have a unit size of 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the device, the unit size corellates with the sound produced by the device.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Endurance Peak 2 by 4mm
, 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JBL Endurance Peak 2 20Hz
JBL Endurance Peak 2's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component 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 produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
JBL Endurance Peak 2 20000Hz
The JBL Endurance Peak 2's highest frequency is at 20000Hz, high-frequency response indicates how well an audio component makes high recognizable frequencies and if it makes any adjustments to the signal on its way through.
Sony WF 1000XM4's highest frequency is at 40000Hz, this means that
Sony WF 1000XM4 generate a clearer and crispier treble than the JBL Endurance Peak 2
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
JBL Endurance Peak 2 93dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, JBL Endurance Peak 2'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. How loud a device 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

JBL Endurance Peak 2 ✗
The 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 sound pressure level, with the use of high magnetic flux.
