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.
