The Bose QuietComfort 2 have a unit size of 9.3mm in diameter, bigger drivers are more powerful, therefor producing better bass. A driver unit is the component that produces sound in the device, its size corellates with the sound made by the earbuds. Sennheiser Momentum 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort 2 by 2.3mm
, 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 yeah, larger drivers are capable of generating louder sound, but this does not imply that they deliver better quality sound. Bose QuietComfort 2's lowest frequency is at 20Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it alters the signal while at it. Sennheiser Momentum 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum 3 can produce a juicier bass than the Bose QuietComfort 2
The Bose QuietComfort 2's highest frequency is at 20,000Hz, high-frequency response indicates how well a particular audio component generates high recognizable frequencies and if it makes any changes to the signal on its way through.
Sennheiser Momentum 3's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum 3 generate a clearer and crispier treble than the Bose QuietComfort 2
