In a quiet environment for the Kotion Each G9000, an amplifier with a voltage level of at least -19.50 dBV at 27 Ohms is recommended for listening to music with a level of 90 dB SPL (without noise isolation). If source power is weak, there will be insufficient volume level. If the source is too powerful, then there is a high probability of constantly hearing background noise. High sensitivity of the headphones means less energy need from the source (for portable devices - less power from the battery).ĭepending on the sensitivity, headphones are best to use with sources of optimum power. The sensitivity by power reflects the efficiency of the headphones. The sensitivity by voltage reflects the relative 'loudness' of the headphones among others - the higher is the value, the louder are the headphones. The sensitivity of the Kotion Each G9000 headphones is 123.50 dB/V SPL by the voltage and 107.74 dB/mW SPL by the power. Recording a voice or instrument in the studio
