ANC makes use of advanced technology to actively counter noise. How it works, it listens to the sound pattern of incoming noise and after generates a mirror signal to cancel it out. Simply put, it's like taking +1 (noise) and adding -1 (counter sound by the device) giving 0 hence "diluting" the noise.
Samsung Galaxy Buds 2 Pro have ANC enabling you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.

Driver Unit Size
Samsung Galaxy Buds 2 Pro
10mm
Ultimate Ears Drops 9.2mm
The Ultimate Ears Drops have a unit size of 9.2mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the device, its size determines the loudness of the earbuds.
Samsung Galaxy Buds 2 Pro driver unit is 10mm in diameter,
making them have a larger driver unit than that of Ultimate Ears Drops by 0.8mm
, 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 indicate that they produce better quality sound.
Lowest Frequency
Samsung Galaxy Buds 2 Pro
20Hz
Ultimate Ears Drops 20Hz
Ultimate Ears Drops's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio component produces low frequencies that can be heard, and if it makes any changes to the signal while at it.

both devices can make sound with equal bass
Highest Frequency
Samsung Galaxy Buds 2 Pro

both devices can generate equal treble
Sound Pressure Level
Samsung Galaxy Buds 2 Pro
25dB/mW
Ultimate Ears Drops 110dB/mW
SPL, is the pressure level of sound, measured in decibels, dB, Ultimate Ears Drops's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Samsung Galaxy Buds 2 Pro's sound pressure level measurement is 25dB/mW. How loud 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.
