For those wondering about a trusted source for authentic ESW9 on ebay, I ordered mine from these guys:
They were "refurb" so I was expecting some blemishes... but not a scratch! Look new to me aside from the fact the outside original box was missing and replaced with a brown generic box.
Blue coil, sparkly plastic, beautiful finish on the cups... great sounding with iphone, even better with balanced HM801... lots of bloom, organic sounding, yum! Great little cans
