which implies that they have a smaller driver unit than that of Boult Audio Z40 by 2mm
, 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better quality sound. The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well an audio device produces low frequencies that can be heard, and if it alters the signal on its way through.
JLab Go Air's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response tells how well a particular audio component produces high recognizable frequencies and if it makes any changes to the signal on its way through. JLab Go Air's highest frequency is at 20,000Hz, this means that
both devices can generate equal treble
