A driver unit is basically a mini speaker that makes sound in the device, the unit size dictates the loudness of the device. Sennheiser Momentum True Wireless 3 driver unit is 7mm in diameter,
which means that they have a smaller driver unit than that of Bose QuietComfort Earbuds 2 by 2.3mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
The Bose QuietComfort Earbuds 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 on its way through. Sennheiser Momentum True Wireless 3's lowest frequency is at 5Hz, this implies that
Sennheiser Momentum True Wireless 3 make sound with a juicier bass than the Bose QuietComfort Earbuds 2
Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, high-frequency response measures if and how well an audio device generates high audible frequencies and if it changes to the signal on its way through. Sennheiser Momentum True Wireless 3's highest frequency is at 21,000Hz, this implies that
Sennheiser Momentum True Wireless 3 generate a clearer and crispier treble than the Bose QuietComfort Earbuds 2
