The sensitivity of headphones refers to the relationship between the strength of the audio input signal and the sound output by the headphones. Specifically, it represents the loudness of the sound produced by the earphones when receiving the same audio input.
The sensitivity of regular headphones is usually between 90db and 110db, while high sensitivity headphones can reach 120db or even higher. Compared to low sensitivity earphones, high sensitivity earphones can output louder sound at lower volume, resulting in a better experience.
In addition, the sensitivity of headphones is also related to the quality of the input signal. If the input signal remains normal under various conditions, headphones with higher sensitivity can bring a better experience. However, if the input signal is small or there is noise interference, headphones with higher sensitivity may feel more fatigued and may also be more prone to hearing damage.
Finally, it should be noted that the sensitivity of headphones is only one aspect of their performance and should not be the only factor in choosing headphones. Other factors, such as frequency range, sound quality, comfort level, etc., should be considered when selecting headphones.
