Has Active Noise Cancellation (Noise Control)
Sony WF 1000XM4
✓
Beats Fit Pro ✓
ANC utilises more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and after inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) then adding -1 (counter sound by the device) to make zero hence "diluting" the noise.
Beats Fit Pro 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 overcome background noise.
Sony WF 1000XM4 too have ANC which makes either of the devices ideal for flights and rush hour travels. The Beats Fit Pro and Sony WF 1000XM4 work with different noise cancellation settings, pick the setting that you prefer for commute or that suites your relaxation time.
Has Passive Noise Reduction

✓
Beats Fit Pro ✓
Beats Fit Pro stay tightly in place, creating an acoustic seal that reduces your environment sounds while preventing the device voice audio from leaking out at the same.
Both of these devices have passive noise reduction this means that they reduce ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Beats Fit Pro 9.5mm
Beats Fit Pro have a unit size of 9.5mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, 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 Beats Fit Pro by 3.5mm
, 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Sony WF 1000XM4
20hz
Beats Fit Pro 20hz
The Beats Fit Pro's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio device generates low audible frequencies and if it alters the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this implies that
both devices make sound with equal bass
Highest Frequency
Sony WF 1000XM4
40,000hz
Beats Fit Pro 20,000hz
Beats Fit Pro's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular 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 40,000Hz, this means that
Sony WF 1000XM4 generate a clearer and crispier treble than the Beats Fit Pro
Sound Pressure Level
Sony WF 1000XM4
105db/mw
Beats Fit Pro 101.3db/mw
SPL, is the level of pressure of sound, measured in decibels, dB, Beats Fit Pro's measurement is 101.3dB/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. The sound pressure level, a device is can be taken differently by separate persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
Sony WF 1000XM4
✓
Beats Fit Pro ✓
Beats Fit Pro have neodymium magnets, when used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help generate music at quite a high sound pressure level, with the use of high magnetic flux.
Sony WF 1000XM4 have it too, devices with these magnets are lighter and more powerful than those which use ferrite magnets. It is also known that they have more bass and clearer high notes.
