JBL Live Free 2 ✓
Active noise cancellation utilises advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern of incoming noise and inverts the soundwaves to cancel it out. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) to make 0 thus "diluting" the noise.
JBL Live Free 2 have ANC allowing you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the earbuds volume to outcompete background noise.
Sony WF 1000XM4 too have Active Noise Cancellation making either of the devices ideal for plane rides and rush hour travels. Each work with different noise cancellation settings, pick the mode that you prefer for travel or that enhances your chill time.

Driver Unit Size
Sony WF 1000XM4
6mm
JBL Live Free 2 11mm

A driver unit is the component that makes sound in the device, its size dictates the loudness of the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which means that they have a smaller driver unit than that of JBL Live Free 2 by 5mm
, 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 are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM4
20hz
JBL Live Free 2 20hz
JBL Live Free 2's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component generates low frequencies that can be heard, and if it makes any changes to the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40,000hz
JBL Live Free 2 20,000hz
The JBL Live Free 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio component makes high audible 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 generate a clearer and crispier treble than the JBL Live Free 2
Sound Pressure Level
Sony WF 1000XM4
105db/mw
JBL Live Free 2 102db/mw
The sound pressure level, is the level of pressure of sound, measured in decibels, dB, JBL Live Free 2's measurement is 102dB/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 something is can be considered differently by different people, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet

JBL Live Free 2 ✗
Sony WF 1000XM4 have neodymium magnets, if 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, with the use of high magnetic flux.
