Sensitivity
Headphone sensitivity measures how loud a pair of headphones will be at a given signal strength. Headphones with higher sensitivity ratings will produce louder sounds than headphones with lower sensitivity ratings. It is measured in dB SPL (decibels of sound pressure level) per unit of power (typically 1 milliWatt) or sometimes unit of voltage (typically 1 Volt) from the source at a frequency of 1 kHz.
|
110 dbSPL (passive : 1 kHz/1V RMS) |
|
Total Harmonic Distortion (THD)
When driving headphones at high volumes, it is possible for the diaphragm (the ‘speaker’ inside the headphones) to be unable to move fast enough. This leads to distortion, manifesting itself as crackling, popping or the alteration of musical notes. Most headphones will fall below 1% THD.
|
<0,5% @ 100 dBSPL / 1kHz |

Frequency Response
Headphone frequency response refers to the frequency-specific sensitivity of the output. Frequency responses show the range that headphones are capable of reproducing—a graph shows which frequencies are accentuated over others. The ideal range covers the audible sound range of 20 Hz – 20 kHz.

17 – 23,000 Hz (-10db) |
