Up for sale is a used Sony/Kimber MUC-B30UM1 for the Sony MDR-Z1R’s or MDR-Z7’s. It‘s the 6.3mm version of the cable and it is 3 meters in length. I’m asking $130 dollars for the cable, including shipping and fees. I’m selling to fund an upgrade to Kimber Kable Axios Cu. Here’s a chance to get a great upgrade for your Sony’s. I don’t have the original box for the cable, but it will come well protected.
