Active noise cancellation makes use of more advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) to make 0 hence "diluting" the noise.
Anker Soundcore Liberty 3 Pro have ANC enabling you to listen at lower volume levels, good for your ears since you don't have to crank up the device volume to outcompete background sounds.

A driver unit is basically a mini speaker that makes sound in the device, its size determines the loudness of the earbuds.
Anker Soundcore Liberty 3 Pro driver unit is 10.6mm in diameter,
which implies that they have a smaller driver unit than that of Urbanista Copenhagen by 1.4mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound.

Anker Soundcore Liberty 3 Pro
20Hz
Urbanista Copenhagen 20Hz

both devices can make sound with equal bass
Highest Frequency
Anker Soundcore Liberty 3 Pro
40000Hz

Anker Soundcore Liberty 3 Pro can produce a clearer and crispier treble than the Urbanista Copenhagen
Sound Pressure Level
Anker Soundcore Liberty 3 Pro
92dB/mW
Urbanista Copenhagen 115dB/mW
The sound pressure level, is the pressure level of sound, in decibels, dB, Urbanista Copenhagen's measurement is 115dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Anker Soundcore Liberty 3 Pro's sound pressure level measurement is 92dB/mW. How loud something is can be taken differently by different persons, so we need to have the means to get an objective measurement of sound level expressed in numerical terms.
