The response frequency of headphones refers to the frequency range of sound that the headphones can respond to. Generally speaking, headphones with a wider frequency range can play more audio details and richer timbres. The response frequency of headphones is usually measured in Hertz (Hz), representing the number of vibrations per second. The frequency range that can be heard by the human ear is usually between 20Hz and 20kHz.
The frequency response of headphones can affect the performance of music. Earphones with poor frequency response may not be able to play all the details of high-frequency sound or low-frequency music. For example, headphones lacking low-frequency response may not be able to play the tremors of bass guitars and the strong beat rhythm of low-frequency drums. If the high-frequency response of audio is poor, then Percussion instrument, choruses and other high-frequency content may sound far from clear.
Generally speaking, for music appreciation, most people do not need high-end headphones with a wide frequency response range. For music production or recording, it is necessary to use headphones with a wide frequency response range to ensure that all music information can be captured and processed.
