I most say, it seems unprofessional that hifiman has done nothing to proper dampen their 'phones with their pleathers.
I see what you mean by ringing even though I could not identify it myself, but after all I am not as experienced yet . I especially find it to be present with acustic guitars with the metal strings. It seems kinda sharp and uncontrolled. In some songs it seems to cause listening fatigue.
Also, Jerg, what did you do with the foam ring inside the pads?
