Shame you're not located in EU, if you were I'd be more than glad to take the PHs off your hands! I was on holiday abroad at the time and my wallet was weeping when those dropped but they'd match my room so well, my headphone stand has purpleheart wood, my keyboard wrist rest is made of purpleheart, my keycaps are violet, my headphone cable sleeving is purple... I like purple. I also like bass, so I'm gutted I had to pass on them - hoping a second hand pair in new condition within EU comes by at some point in time.
PS: I also agree that most high end headphones, asides the ones that are overpriced to begin with, are quite easy to sell nowadays.
You will find some. Look at what happened with the Mahogany...
At first launch, they were a little hard to get (sold really fast), but as time went on, they popped up more often on the f/s.
