which means that they have a smaller driver unit than that of Technics EAH AZ100 by 4mm
, as many tend to believe 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 produce better quality sound. The Technics EAH AZ100's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component produces low recognizable frequencies and if it makes any changes to the signal while at it.
Sony WF 1000XM4's lowest frequency is at 20Hz, this means that
both devices produce equal bass
Technics EAH AZ100's highest frequency is at 40,000Hz, high-frequency response tells how well a particular audio component generates high audible frequencies and if it makes any adjustments to the signal on its way through. Sony WF 1000XM4's highest frequency is at 40,000Hz, this implies that
both devices can generate equal treble
The Technics EAH AZ100's battery life is 12 hours, these last longer than 5 hours of listening which is considered average for a single charge. A device's battery life is given by the manufacturer, and with more battery hours, you get to use it for longer and have to charge the device less often.
Sony WF 1000XM4's battery life is
less than that of Technics EAH AZ100 by 4 hours
