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.

More detailed
Measurements of Sennheiser HD 558 were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The Sennheiser HD 558 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.
I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a source amplifier and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.

Condition: New - Brand New Factory Sealed!] on Scamazon and procured through a now deprecated and deleted seller by the name of [T.R.G] with a waveform in the logo and great reputation: [98% positive lifetime (23581 total ratings)] So I knew I would be getting genuine Sennheiser(even though this was of little concern in 2015...) Well, it may not be concise, but this is my review of these headphones, with complete positive biases, as I haven't dared put anything else over my ears, and trying to avoid putting things in my ears unless by necessity. I do miss my Shure IEM's though, gone with the wind-now..
