Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
JBL Tune 225TWS ✗
Active noise cancellation utilises advanced technology to actively cancel noise. How it works, it studies the sound pattern outside and inside the earbud and inverts the soundwaves to counter it. Simply put, it's like having +1 (noise) then adding -1 (counter sound by the device) giving zero hence "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 need to crank up the earbuds volume to overcome background noise.
Has Passive Noise Reduction

JBL Tune 225TWS ✓
The JBL Tune 225TWS stay tightly in place, this creates an acoustic covering that reduces your environment noise and also prevents the earbuds sound from leaking out .
Both Sony WF 1000XM4, and JBL Tune 225TWS have passive noise reduction which means that they reduce ambient noise without using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
JBL Tune 225TWS 12mm
JBL Tune 225TWS have a unit size of 12mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
A driver unit is basically a mini speaker that makes sound in the device, its size corellates with the loudness of the earbuds.
Sony WF 1000XM4 driver unit is 6mm in diameter,
which implies that they have a smaller driver unit than that of JBL Tune 225TWS by 6mm
, a common assumption 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 indicate that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
JBL Tune 225TWS 20Hz
The JBL Tune 225TWS'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 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 Tune 225TWS 20000Hz
The JBL Tune 225TWS's highest frequency is at 20000Hz, high-frequency response measures if and how well a particular audio device generates high audible 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 produce a clearer and crispier treble than the JBL Tune 225TWS
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
JBL Tune 225TWS 105dB/mW
The sound pressure level, is the pressure level of sound, in decibels, dB, JBL Tune 225TWS's measurement is 105dB/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 people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
JBL Tune 225TWS ✗
The Sony WF 1000XM4 have neodymium magnets, if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, with the use of high magnetic flux.
