Measurements of Koss ESP950 Alcantara were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The Koss ESP950 Alcantara 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.

That's my headphones :).
Is the "Alcantara" the original pads?
I think the other Koss 950 measurement with the "leather cushions" seems a bit better to me..
So I consider changing the original pads to leather.
