General results Koss ESP 950 Default cushions without the shell
- The type of acoustic design: Open
- Type of headphones: Over-ear
This is a simplified report for non-professional users ("dummies"), poorly versed in the headphones characteristics and specialized graphs.
In this report, information is presented as simply and clearly as possible. Interpretation of data is maximally simplified, and, accordingly, devoid of subtleties and nuances. This is sufficient for an overall assessment, but for a more complete and accurate presentation should be considered a professional type report
.
By possible, the characteristics are accompanied by explanations to do reader possibility gradually master a more complex professional report of Koss ESP 950 Default cushions without the shell.

Analogy of the report
For example when choosing a video card, many people do not understand the set of tables with the final data of the test packages. How to understand the relative difference in these figures? In most cases, the unprepared reader is satisfied with only the textual evaluation of the author, without delving into the figures. When the choice of a product is done thoroughly, then the reader gradually deepens into complex tables, mastering information from simple to complex. We made two separate reports: "simple" and "complex". A simple report with explanatory comments will allow you to self-study to gradually understand and professional report.С 2024 года измерения полноразмерных наушников в RAA проводятся не только на инструментальных стендах, но и вживую с помощью разработанной системы в RAA - Live Measurement System. Это позволяет увидеть реальное поведение наушников и их вариативность звучания относительно стандартных стендов. Результаты таких измерений в отчетах обозначаются как со стендов Human. В этом отчете - это:
Т.к. АЧХ зависит от посадки наушников и их прогрева/износа, то в RAA была разработан универсальный комплект Live Measurement System
для контроля своих наушников на собственной голове. Типовые комплекты доступны для приобретения.
shows the frequency volume balance (tonal balance) similar to the equalizer setting enabled for headphones or speakers with "even frequency response". The frequency response can be used to estimate the volume balance between frequency ranges and a type of frequency response. The average level is taken for 0 dB. Where the values are negative, the frequency ranges are quieter than the average level, and where positive, on the contrary, louder.
In ideal conditions, headphones should have the same frequency response as speakers with flat frequency response. But due to the complex shape of the human auricle, we have increased sensitivity in the high frequency region. he frequency response from the sound source varies depending on the rotation of the head to this source. Thus, the frequency response of the headphones should correspond to the conditional target frequency response, which should be subjectively close to the smooth perception of sound in the headphones.
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 perception of frequency response additionally depends on various external conditions, whether we listen to headphones quietly or loudly, on the street or at home, whether the headphones have noise insulation or not, etc.
To evaluate the sound of headphones for yourself, you need to add various corrections to the base target curve and get the final target curve - a multitarget.
The graph additionally shows the target curves for listening to headphones at different volumes. The middle line correlates with the natural volume, which in turn can be different for different genres of music: from 70 dB SPL for acoustic recordings to 90 dB and above for heavy rock music. Here, the deviation of the volume at which the headphones are listened to from the volume at which the music would sound live is estimated.
The upper line shows the desired frequency response of the headphones for listening at a low volume, 20 dB below the natural level. This can be listening to music at night or listening in the background while working or relaxing. As the volume decreases, we subjectively feel the lowest and highest frequencies more quietly than the middle frequencies.
The bottom line, on the contrary, shows the desired frequency response for louder listening, above the natural volume by 20 dB.
More settings for the target curve are presented in the Multitargeting / Equalizer Settings report, and you can configure the target curve in detail and upload settings for the equalizer on the frequency response comparison page (you can go to it using any graph in this report).
Also, the frequency response of the headphones changes when connected to different sources due to the mutual unevenness of the headphone impedamce and the amplifier impedance
. The professional report provides the most common source options and changes in the final frequency response. In the RAA comparison tools
, it is possible to connect various measured headphones and sources in the constructor, and compare such bundles with each other.
The frequency response depends on the measurement stands used. Since all the stands are simplified or averaged models of people, the results are approximate. The most accurate graph can be obtained only by individually measuring the headphones on your own head

More detailed
Measurements of Koss ESP 950 Default cushions without the shell were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The Koss ESP 950 Default cushions without the shell 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.
