The response frequency of earphones refers to the frequency range that the earphones can cover, which is the sound performance ability of the earphones at different frequencies. Generally speaking, the frequency range that humans can hear is between 20Hz and 20kHz, so the earphone response frequency should cover at least this range.
If the response frequency range of the earphones is insufficient, it can cause problems such as tone distortion and inability to hear high or low tones. For example, if the response frequency range of headphones can only cover 500Hz-8kHz, then when listening to music, there will be a lack of bass and treble, and the overall sound quality will be relatively flat.
Therefore, the wider the response frequency range of headphones, the more realistic the sound and better the sound quality can be presented. Of course, in addition to the response frequency, there are many other factors that can also affect the sound quality of headphones, such as sensitivity, distortion, impedance, and so on. Therefore, when choosing headphones, we not only need to focus on the response frequency range, but also consider multiple aspects comprehensively.
