Comparison the frequency response of headphones

How much frequency response of the Cardas EM5813 different from other models?
Comparison the frequency response graph of Cardas EM5813 on-line.

Comparison of frequency response and sensitivity.

Comparison of basic characteristics

How much are the characteristics of Cardas EM5813 different from other models?
Compare the Cardas EM5813 with other tested headphone models

In the general table, you can compare the characteristics:
  • Sensitivity of voltage
  • Sensitivity of power
  • Impedance

Determination of the required voltage level from the headphone amplifier and comparison with other models

What voltage range from the amplifier is needed for the Cardas EM5813 ?
Comparison of on-line graphs with additional analytics of compatibility with specific amplifiers.

In comparison, the required voltage value, which the amplifier should provide for the selected sound pressure, is determined. According to the voltage graphs from the measured amplifiers, built according to the "musical" power, you can select the most successful amplifiers for the Cardas EM5813 headphones. You can select several headphones and several amplifiers in the selection.

The voltage chart for musical power and the relationship with the sensitivity of headphones are developed in RAA

Selection by characteristics

You can use the automatic selection of the optimal AMP models for Cardas EM5813 from the measured power parameters of the amplifying part and the measured parameters of the headphones for different purpose of use.

During the selection of AMPs, they are selected according to the characteristics and on a five-point scale are estimated the optimal bundles of headphones and Cardas EM5813 . The selection takes into account the power characteristics of the amplifier, the sensitivity and resistance of the headphones, as well as the conditions in which the bundle will be used: at home, in the studio, on the street, in the subway, etc. The compatibility analysis is similar to car analysis based on its clearance - on which road the car will optimally go without evaluating the class of the car.

A detailed description in plain language on an example with Cardas EM5813 is in the simple report for "dummies".

The selection method by characteristics is developed in RAA.
