I have for sale my Yuin OK1 that has been very neatly recabled with 5n silver cable. There is no box or accessories as I received the headphone in exactly the same condition. The only visible wear is a tiny nick in the shrink-wrap of the main cable. It in no way affects the excellent performance of this headphone. Cable is approximately 4' long and can be coiled in about a 4" circle. I would not suggest crumpling and stuffing in a pocket. This is a serious headphone.
Price is $175 which includes shipping and paypal fees to CONUS location.
