This is going to be the new standard. Managed to snag a brand new he-500 for $500 from an authorized seller.
Talked a guy on Amazon from 400 to 230 on a barely used Ultrasone Pro 2900. I was pretty damn satisfied with that.
Not the cheapest / sweetest deal in the world, but I got the Annie's + E07K/E09K and a L9 cable for around USD354 [BND425]. Sony XBA-4 from JPN for around USD200?
Brand new Shure SRH 1840 for 450 during a sale while it was priced around 700 back then. I still got it cheaper then the current prices.
