Frequency response refers to the difference in the sound emitted by headphones at different frequencies. It is one of the important indicators for measuring the sound quality of headphones. In the parameter description of headphones, there is often a frequency response range, such as 20Hz to 20kHz. This means that the headphones can output audio signals in the frequency range from 20 Hz to 20 kHz. The wider the frequency response, the wider the range of sound that can be expressed.
When choosing headphones, a good frequency response range is usually 20Hz-20kHz, which covers the vast majority of sounds that humans can hear. However, some headphones have a frequency response that exceeds this range, such as those specifically designed for professional audio production, which may have a wider frequency response range of 5Hz-50kHz or higher.
It should be noted that frequency response is not the only indicator of earphone sound quality. The sound quality of headphones is also affected by other parameters, such as distortion rate and sound separation. Therefore, when choosing headphones, it is important to consider them comprehensively and choose headphones that meet personal needs.
