These are one of a kind built by me. They sound amazing. Imagine PS - 500 with better detail and clarity across all frequencies.
They are the easiest to drive of all high end headphones I have tried (straight out of the sansa fuze playing FLAC) but scale well with better equipment.
I am also listing a Rhydon full build Magnum, but will only sell one of these so the first sale negates the other.
I will cover PP and shipping in the US.
