This is the earphone case and cable that come with the TANGZU Nezha. Perhaps because it's an accessory for a higher-end model, it's large enough to store the earphones separately for the left and right sides. The cable is a 4-core braided type, with high-purity single-crystal copper (OCC) wire and a 0.78mm 2-pin (flat) connector. Also, the plug is interchangeable, with 3.5mm and 4.4mm plugs included. Since I only used the earphone unit itself, both the case and cable are unused. I will also include the unused ear tips that are left over. How about for storing your earphones and for re-cabling? Since this is a used item, please refrain from returns or claims. TANGZU Chinese earphones Re-cable Earphone case kz THIEAUDIO 2Pin Flat
