Has Active Noise Cancellation (Noise Control)

✓
Samsung Galaxy Buds 2 Pro ✓
ANC uses more advanced kind of tech to actively cancel noise. How it works, it listens to the sound pattern outside and inside the earbud and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 (noise) then producing -1 (counter sound by the device) to make zero which results in a reduced level of noise.
The Samsung Galaxy Buds 2 Pro have ANC enabling you to listen at lower volume levels, good for your ears since you don't need to crank up the earbuds volume to overcome background noise.
Sony WF 1000XM4 too have Active Noise Cancellation which makes both devices ideal for plane rides and morning travels. The Samsung Galaxy Buds 2 Pro and Sony WF 1000XM4 operate with different noise cancellation types, pick the mode that suits your commute or that suites your relaxation time.
Has Passive Noise Reduction

Samsung Galaxy Buds 2 Pro ✓
Samsung Galaxy Buds 2 Pro stay tightly in place, this creates an acoustic seal that tones down background noise while preventing the device music from leaking out .
Both of these devices have passive noise reduction this implies that they tone down ambient noise without using ANC to cancel it out.
Driver Unit Size
Sony WF 1000XM4
6mm
Samsung Galaxy Buds 2 Pro 10mm
Samsung Galaxy Buds 2 Pro have a unit size of 10mm in diameter, the bigger the unit the more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, the unit 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 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 yes, larger drivers can generate louder sound, but this does not imply that they produce 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 measures if and how well an audio device produces low recognizable frequencies and if it makes any changes to the signal on its way through.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
Sony WF 1000XM4
40000Hz
Samsung Galaxy Buds 2 Pro 20000Hz
The Samsung Galaxy Buds 2 Pro's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component produces high audible frequencies and if it makes any adjustments to the signal while at it.
Sony WF 1000XM4's highest frequency is at 40000Hz, this implies that
Sony WF 1000XM4 generate a clearer and crispier treble than the Samsung Galaxy Buds 2 Pro
Sound Pressure Level
Sony WF 1000XM4
105dB/mW
Samsung Galaxy Buds 2 Pro 25dB/mW
The sound pressure level, is the pressure level of sound, measured 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. How loud something is can be taken differently by separate persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
Has A Neodymium Magnet

Samsung Galaxy Buds 2 Pro ✗
The Sony WF 1000XM4 have neodymium magnets, if used in earbuds produce a higher sensitivity and substantial sound output using less power to do so. They can help generate music at quite a high SPL, with the use of high magnetic flux.
