Unused [8-Core 4N Oxygen-Free Copper Silver-Plated Upgrade Cable] The KBEAR ST12 upgrade cable series uses high-purity, thick cables, with a single 14-core structure, totaling 112 cores. This rich core count and scientific braiding effectively improves the sound expression of earphones. The KBEAR ST12 is an oxygen-free copper silver-plated upgrade cable. The fusion of single crystal copper and silver-plated wire takes full advantage of the strengths of both: copper provides powerful low frequencies and a cohesive mid-range, while silver enhances the performance of high frequencies to the finest details, making the audio clearer. High-purity materials improve the wire's transmission performance. [Aluminum Anodization Process] The KBEAR ST12 upgrade cable uses a metal plug with an aluminum anodization process. A soft tape protective layer is added to the cable connection to prevent bending and breakage, making it safer to use.
