Brief information

The graph shows the frequency response of the headphones without compensation to the target curve. Additionally, the basic target curve is shown. The frequency response depends on the measurement stands used. Since all artificial stands are simplified or averaged models of people, the results are always approximate.

The HDM-X stand uses the concept of a binaural microphone with microphone caps positioned at the entrance to the ear canal. The unevenness in the high frequency range above 2~3 kHz is formed from the shape of the auricle, the fit of the headphones on the stand and the relative internal volume between the ear and the driver. There is no resonance from the ear canal in this type of stand.

Since 2024, all headphones are measured on the head of the founder of the RAA project and in some cases on the head of the owners of the headphones as part of an individual calibration.The stand for live measurements is called both Human + Human identifier. Such a measurement has not yet been performed for Sony WH-1000XM4, but if possible, such a measurement will be added. Such measurements show the low-frequency and mid-frequency range most accurately, since they take into account the real pressure of the ear pads and damping of the real head. The high-frequency range in this measurement is less accurate, because it depends on the fit of the microphone in the ear.

For overhead and full-size headphones, the basic target curve RAA v1 with low-frequency correction from Harman Target Curve Over-Ear 2018 is given.

The combined frequency response of the Sony WH-1000XM4 Bluetooth with various amplifier sources is shown in an additional summary report.

The export of the frequency response graph is available on the comparison pages, which can be accessed using any graph from the report below. A separate summary report shows the recommended Sony WH-1000XM4 Bluetooth equalization settings and a comparison with various target curves.

Clicking on the graph will take you to the comparison page of different models with advanced graph display settings.

More detailed

Measurements of Sony WH-1000XM4 Bluetooth were carried out by Roman Kuznetsov on the hardware-software complex RAA.

The Sony WH-1000XM4 Bluetooth 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.
