Explanations of Headphones Technical Specifications

--Frequency Response

When we are buying headphones, it will be helpful to have a basic understanding of the technical specifications of the headphones to make a purchase decision. Generally, the information we need can be found on the outer box of the headphones. The types of information in this part include the type of headphones, frequency response, speaker impedance, wire length, etc.

Frequency Response

The frequency response of the headphones refers to the frequency range in which the speaker plays sound at high gain. Normally headphones have a range of frequency response from 12-22Hz on the low end to 20-22KHz on the high end. Therefore, if the headset has a listed frequency response of 20 Hz-20 KHz, it can play sound from 20 Hz to 20 KHz with good gain that can be heard by users. The headphones will not be able to play sounds beyond the range of these frequencies, but they can play sounds between it. And that’s why this range represents the headphones' bandwidth.
