Active noise cancellation uses advanced technology to actively counter noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and inverts the soundwaves to cancel it out. Simply put, it's like having +1 (noise) then adding -1 (inverted noise) giving zero which results in a reduced level of noise.
Samsung Galaxy Buds 2 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 outcompete background sounds.
The Sony WF 1000XM4 too have ANC which makes both devices ideal for plane rides and morning commutes. Each operate with different noise cancellation modes, pick the setting that suits your travel or that suites your chill time.

which means that they have a smaller driver unit than that of Samsung Galaxy Buds 2 Pro 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 it's true that, 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
Samsung Galaxy Buds 2 Pro 20hz
The Samsung Galaxy Buds 2 Pro's lowest frequency is at 20Hz, low-frequency response inidcates 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
40,000hz
Samsung Galaxy Buds 2 Pro 20,000hz
The Samsung Galaxy Buds 2 Pro's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio component produces high recognizable frequencies and if it changes to the signal while at it.

Sound Pressure Level
Sony WF 1000XM4
105db/mw
Samsung Galaxy Buds 2 Pro 25db/mw
SPL, is the level of pressure of sound, in decibels, dB, Samsung Galaxy Buds 2 Pro's measurement is 25dB/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 considered differently by separate people, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet
