ANC makes use of more advanced kind of tech to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and then generates a mirror signal 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 0 therefore "diluting" the noise.
Samsung Galaxy Buds 2 Pro have Active Noise Cancellation allowing you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the device volume to outcompete background sounds.

Driver Unit Size
Samsung Galaxy Buds 2 Pro
10mm
Sony WF C500 5.8mm
The Samsung Galaxy Buds 2 Pro driver unit is 10mm in diameter, bigger drivers are more powerful, therefor producing better bass.
The driver unit is basically a mini speaker that makes sound in the device, the unit size determines the sound produced by the earbuds.
Sony WF C500 driver unit is 5.8mm in diameter,
which means that they have a smaller driver unit than that of Samsung Galaxy Buds 2 Pro by 4.2mm
, many people have a misconception 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
Samsung Galaxy Buds 2 Pro
20Hz
Sony WF C500 20Hz
The Samsung Galaxy Buds 2 Pro's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio device produces low frequencies that can be heard, and if it alters the signal on its way through.
Sony WF C500's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
Samsung Galaxy Buds 2 Pro
20000Hz
Sony WF C500 20000Hz
Samsung Galaxy Buds 2 Pro's highest frequency is at 20000Hz, high-frequency response indicates how well an audio device produces high audible frequencies and if it makes any changes to the signal while at it.
Sony WF C500's highest frequency is at 20000Hz, this implies that
both devices can generate equal treble
Sound Pressure Level
Samsung Galaxy Buds 2 Pro
25dB/mW
Sony WF C500 ✗
The sound pressure level, is the level of pressure 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.
Has A Neodymium Magnet

Sony WF C500 ✓
Sony WF C500 have neodymium magnets, when used in earbuds produce a higher sensitivity and substantial sound output while using less power. They can help generate music at quite a high SPL, with the use of high magnetic flux.
