Comparison of the parameters

Comparison the frequency response of headphones

Comparison the frequency response of headphones:

• Relative to frequency
• Relative to sensitivity

It is possible to display the graph lines, areas and "bars". You can adjust the scale of the graph. After setting up the comparison, you can share a reference to the comparison chart.

Some models of headphones have been tested for a long time on the stands of the last generation and do not take part in the comparison. If possible, we will re-test these headphones on modern stands.

Comparison of the combined frequency response of a bundle of headphones and an amplifier

Comparison the frequency response of a bundle of headphones and an amplifier:

• Total frequency response
• Only change of frequency response

You can adjust the scale of the graph. After setting up the comparison, you can share a reference to the comparison chart.

Some models of headphones have been tested for a long time on the stands of the last generation and do not take part in the comparison. If possible, we will re-test these headphones on modern stands.

Comparison of basic characteristics of headphones

In the table, you can compare the characteristics:

• Sensitivity to voltage (dB/V SPL)
• Sensitivity to power (dB/mW SPL)
• Impedance

For convenience, you can filter by manufacturers, type of headphones, acoustic design and set ranges of sensitivity and resistance.

In comparison, wireless headphones and headphones do not participate in a part of the headphones with active amplification. for such models there is no sensitivity parameter.

Comparison of the basic characteristics of headphone amplifiers

In the table, you can compare the characteristics:

• maximum current levels for equivalent classes A, AB, B and maximum mode
• maximum voltage levels for equivalent classes A, AB, B and maximum mode

Sort and select by the manufacturers.

In comparison, only those amplifiers participate that contain tests in the reports with the distortion spectra of the loads.

Comparison of the power characteristics of the amplifiers and the determination of the required voltage level for the headphones from the amplifier

The required voltage value for the headphones for the selected sound pressure is determined.

The voltage graphs of the measured amplifiers are constructed according to the "musical" power, taking into account the density of the musical signal.

Amplifiers among themselves can be compared in loudness in different power modes for a wide range of loads.

For comparative graphics, you can pick up bundles of amplifications and headphones, where there will be an imbalance with problems from high or low power amplifier or problems with a high-sensitive or low-sensitive headphones.

The optimum voltage from the amplifier is determined only for headphones with measured sensitivity and resistance. In comparison, I participate only in those amplifiers that contain in the reports tests with the spectra of distortions from loads.

Comparison of amplifiers by loudness (Volume Level)

Comparison of amplifiers taking into account the peculiarity of the musical signal for two assignable loads (headphone impedances).

Because of the higher resistance of the headphones, when comparing the volume for a musical signal, it is necessary to simultaneously take into account the current and voltage limits, while the amplifiers for the speakers have only a current limitation. For the exact difference between the amplifiers in dB, the power value must be converted into voltage in units of dBV, taking into account the current margin for the music signal to 12 dB.

In comparison, I participate only in those amplifiers that contain in the reports tests with the spectra of distortions from loads.
