Active noise cancellation makes use of advanced technology to reduce ambient sounds. How it works, it studies the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) and producing -1 (counter sound by the device) giving zero which results in a reduced level of noise.
Beats Fit Pro have Active Noise Cancellation allowing you to listen at lower volume levels, good for your ears since you don't need to crank up the device volume to overcome background noise.
The Sony WF 1000XM4 too have Active Noise Cancellation which makes either of the earbuds ideal for plane rides and morning travels. Each operate with different noise cancellation modes, pick the mode that you prefer for commute or that enhances your relaxation time.

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.
A driver unit is the component that produces sound in the earbuds, its size determines the sound made by the device.
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
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so it's true that, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Sony WF 1000XM4
20Hz
Beats Fit Pro 20Hz
Beats Fit Pro's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component produces 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 implies that
both devices produce 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 human frequencies and if it adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that
Sony WF 1000XM4 can 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 pressure level 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. How loud something is can be taken differently by different persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
