I was looking for a pair of used RS-1 to bring me home after visiting US relatives. Since the headphones would be shipped to my relatives months prior to my arrival and I would have no chance to keep on the pulse of the delivery, I looked for a seller with impeccable reputation. "Salty Peanuts" Haj fit that bill.
Communication proved to be a little late, though, so I frankly started to worry. Well, it turns out Haj was moving and had every good reason to be incommunicado for a while, so ... relieved breath. My relatives have confirmed the arrival of the headphones and say they look very good. I will have a chance to check them out soon.
But if anyone should experience similar delays in communication with Haj later, I would tell them not to worry.
(Report on state of headphones to be updated in a few weeks; I expect it to be good.)
