Ultimate Ears UE Fits ✗
ANC uses more advanced technology to actively cancel noise. How it works, it studies the sound pattern of incoming noise and generates a mirror signal to counter it. Simply put, it's like taking +1 (noise) then producing -1 (inverted noise) giving 0 resulting in a reduced level of noise.
1More Evo have ANC enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the device volume to outcompete background noise.

Driver Unit Size
1More Evo
10mm
Ultimate Ears UE Fits 10mm

Ultimate Ears UE Fits driver unit is 10mm in diameter,
making both devices similar in how loud their sound can get
, a common assumption that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
Lowest Frequency
1More Evo
20hz
Ultimate Ears UE Fits 20hz
The 1More Evo's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low audible frequencies and if it makes any changes to the signal on its way through.
Ultimate Ears UE Fits's lowest frequency is at 20Hz, this means that
both devices can produce equal bass
Highest Frequency
1More Evo
40,000hz
Ultimate Ears UE Fits 20,000hz
1More Evo's highest frequency is at 40,000Hz, high-frequency response tells how well an audio component produces high human frequencies and if it changes to the signal on its way through.
Ultimate Ears UE Fits's highest frequency is at 20,000Hz, this implies that
1More Evo generate a clearer and crispier treble than the Ultimate Ears UE Fits
Sound Pressure Level
1More Evo
✗
Ultimate Ears UE Fits 110db/mw
SPL, is the pressure level of sound, in decibels, dB, Ultimate Ears UE Fits's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
