This is a simplified report for non-professional users ("dummies"), poorly versed in the headphones characteristics and specialized graphs.
Information in this report presents in most simple and clear as possible. Interpretation of the data is simplified as much as possible and accordingly devoid of subtleties and nuances. This is sufficient for an overall assessment, but for a more complete and accurate presentation, the professional report should be studied.
By possible, the characteristics are accompanied by explanations to do reader possibility gradually master a more complex professional 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.

The table shows the most common variations of sound sources and the scope of use of AMPs and headphones bundles.
The compatibility rating is similar to car analysis based on its ground clearance - on which road the car will move optimal without evaluating the class of the car.
Detailed description formula of the table of headphones

For different purposes it is best to select individual headphones, and not to look for some universal headphones for all occasions. Unfortunately, some properties of headphones mutually exclude the use of headphones in different situations. True connoisseurs of quality sound use several pairs of headphones. Headphones are compact and do not take up much space, unlike speakers.

Измерения M-Audio IE 40 проведены Романом Кузнецовым на программно-аппаратном комплексе RAA.
Тест M-Audio IE 40 проведен как черного ящика, без учета стоимости и престижа. Это главный принцип измерений и разработки тестов в RAA.
Считаю, что важно делать не абсолютную оценку устройства, а совокупную оценку при совместной работе с усилителем источника и учетом внешних факторов. Это позволяет эффективно раскрывать потенциал всей связки устройств или делать более оптимальный подбор компонентов.
