High-purity silver-plated oxygen-free copper wrapped high-purity oxygen-free copper + silver-plated high-purity oxygen-free copper braided shielding layer + tin foil + high-purity oxygen-free copper braided shielding layer to form a double shielding structure. Moreover, the characteristics of silver make the influence of electromagnetic interference and other radiation on the signal almost zero, and the 100% shielding effect reduces the ubiquitous radiation interference in the car to the bottom. The performance of the signal line is very balanced, the bass and long waves are enthusiastic and the performance is just right, and the treble and short waves are cold and ethereal, and the sense of space is open.
