For sale is a Yinyoo aftermarket cable I bought on Amazon earlier this year. Works for standard 0.78mm 2pin IEMs and 4.4mm jacks like on the ZX300. I don't have a use for it anymore after purchasing IEM cables 10 times its price It's in functionally perfect condition, and cosmetically nothing significant to note. The 2pin and 4.4mm connectors don't have any wear on them and everything still feels very solidly put together. Retail price on Amazon is $29.99, I ask for $19.50 which already includes shipping to CONUS and PP.
