| Sensitivity | 103 dB | 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. |
| Frequency Response | 12 - 43800 Hz (-3 dB) | 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. |
