The Technics EAH AZ80's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low frequencies that can be heard, and if it alters the signal on its way through. Bose QuietComfort Earbuds 2's lowest frequency is at 20Hz, this means that
both devices make sound with equal bass
Technics EAH AZ80's highest frequency is at 40,000Hz, high-frequency response measures if and how well a particular audio device makes high human frequencies and if it adjustments to the signal on its way through. Bose QuietComfort Earbuds 2's highest frequency is at 20,000Hz, this means that
Technics EAH AZ80 generate a clearer and crispier treble than the Bose QuietComfort Earbuds 2
