Sensitivity works hand-in-hand with the impedance of the headphones. They must correspond to each other because they both work hand-

in-hand to regulate sound and produce clear acoustics without distortion. The sensitivity measured by dB SPL/mW. The Bigger dB, The

higher the sensitivity rating. A high sensitivity will get a wide range of power output, but may get some distortion at the same time. Low

sensitivity is harder to damage and not easy distortion, however, it need your device have more power output than high sensitivity one.

Generally smart phones, tablets, and mp3 players need a earphone from 85dB to 120dB. It should be noted that at 120 dB, the human

ear begins to replace the sensation of hearing with that of pain.


Most earphone with low impedance (less than 25Ω) require little power to deliver high audio levels. So it can save your device power.

earphones with higher impedance (25Ω and over) demand more power. But, they are protected from damage caused by overloading. They

can also be used with a wider range of audio equipment.


Frequency response is the range of bass, mids and treble. 20 to 20,000 Hz is generally accepted as the audible frequency range, this is

the standard for most headphones. Some Earphone offer wider ranges (for example, 5 to 33,000 Hz), but better frequency response does

not always mean better sound quality. Below 20 Hz bass frequencies can be felt more so than heard, treble frequencies over 20,000 Hz

are not always audible.
