The average value of sensitivity by voltage for In-Ear and Tablet headphones by measured 726 models is 129.3 dB/V SPL.

The FiiO F5 sensitivity is 0.0 dB/V SPL.

These headphones are 129.3 dB louder than most In-Ear and Tablet headphones.This difference is more a threefold deviation from the mean. It is necessary to carefully choose the source for these headphones.Some devices designed to work with In-Ear and Tablet headphones may not be loud enough for the FiiO F5.

In general, to listen to music with a level of 90 dB SPL in a quiet environment, the amplifier will require a voltage of 99.0 dBV.

It is desirable that the amplifier provides a margin of 12 dB in cases of rare noisy environments or for too quiet recordings. Thus, the amplifier should provide a maximum voltage level not lower than 111.0 dBV.

Excessive volume margin is undesirable, since for analog regulator, the adjustment range is about 40 dB and below that the channels imbalance begins. For a discrete regulator the pitch may be too large. For digital controllers are possible options for adjusting the sound level before a DAC or in a DAC. As a result of that will be decrease the signal-to-noise ratio and accordingly it is probable the appearance of audible noise.

The average sensitivity to power for In-Ear and Tablet headphones is 112.5 dB/mW SPL (average by measured 726 headphone models). The Audeze LCD-2C sensitivity is 0.0 dB / mW SPL. FiiO F5 have lower sensitivity than other headphones of this type. This means that their power consumption is greater and being connected to mobile devices, the operation time of this bundle will be short than of many others.


Measurements of FiiO F5 FiiO RC-B were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The FiiO F5 FiiO RC-B test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.
