PC360 is a HD 555 with a mic.    Not a HD 598

Quote: I remember Pioneer and Sansui (not 100 % sure) have made ribbon headphones before in the 70s-90s, but I don't know how they perform.

Nice, you removed the inner enclosure? How well do they isolate? 

Sorry for your loss    Apparently, there's no serial number on the PXC 450 (not that I know of). I've looked everywhere on mine, and there's no visible serial #
