Urbanista Copenhagen ✗
Active noise cancellation uses more advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. In simple terms, it's like taking +1 (noise) then producing -1 (counter sound by the device) to make 0 resulting in a reduced level of noise.
Sennheiser Momentum True Wireless 3 have Active Noise Cancellation 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 sounds.

The Sennheiser Momentum True Wireless 3 stay tightly in place, this creates a sound covering that tones down background sounds well as preventing the device sound from leaking out at the same.
Driver Unit Size
Sennheiser Momentum True Wireless 3
7mm
Urbanista Copenhagen 12mm
Urbanista Copenhagen have a unit size of 12mm in diameter, bigger drivers are more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the earbuds, its size dictates the sound produced by the earbuds.
Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Urbanista Copenhagen by 5mm
, as many tend to believe 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 can generate louder sound, but this does not imply that they deliver better quality sound.
Lowest Frequency
Sennheiser Momentum True Wireless 3
5Hz
Urbanista Copenhagen 20Hz
The Urbanista Copenhagen's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 can make sound with a juicier bass than the Urbanista Copenhagen
Highest Frequency
Sennheiser Momentum True Wireless 3
21000Hz
Urbanista Copenhagen 20000Hz
The Urbanista Copenhagen's highest frequency is at 20000Hz, high-frequency response shows how well an audio component makes high audible frequencies and if it changes to the signal while at it.
Sennheiser Momentum True Wireless 3's highest frequency is at 21000Hz, this implies that
Sennheiser Momentum True Wireless 3 can produce a clearer and crispier treble than the Urbanista Copenhagen
Sound Pressure Level
Sennheiser Momentum True Wireless 3
107dB/mW
Urbanista Copenhagen 115dB/mW
SPL, is the pressure level of sound, measured 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.
Sennheiser Momentum True Wireless 3's sound pressure level measurement is 107dB/mW. The sound pressure level, something is can be considered differently by different persons, so we need to have a way of getting a standard measurement of sound level expressed in numerical terms.
