Comparison of the parameters





Comparison the frequency response and sensitivity 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.




Comparison of the combined 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.




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.




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 F.A.Q.
  • Maximum voltage levels for equivalent classes A, AB, B and maximum mode F.A.Q.
Sort and select can by of manufacturers.





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.





Comparison of frequency response and sound pressure depending on the applied voltage and impedance of the amplifier

The final graph is displayed through the frequency response to the absolute sound pressure in dB SPL, taking into account the sensitivity of the headphones when the signal is supplied with known voltage and resistance at the output of the amplifier.





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.
