‌The advantages of audio cables are mainly reflected in their physical characteristics, structural design, electrical performance and signal transmission capabilities. ‌

‌Physical characteristics and material selection‌: Audio wires usually use high-quality conductor materials such as high-purity oxygen-free copper (OFC), silver-plated copper or tin-plated copper. These materials have low resistivity, high conductivity and good oxidation resistance. , which can ensure that the audio signal has minimal loss during transmission and maintain the purity and high fidelity of the sound quality. High-end audio cables will also use special alloy materials or multi-layer structures to further improve performance‌1.

‌Structural design‌: Audio cables generally adopt a dual-core or multi-core structure, and the wires are arranged in parallel or use a special braiding method to reduce electromagnetic interference and signal crosstalk. At the same time, the insulation layer of the audio cable also needs to have good electrical properties and mechanical strength to protect the wires from the impact of the external environment‌1.

‌Electrical performance and signal transmission‌: Since the audio cable transmits power signals and the signal amplitude is large, its resistance value has a particularly significant impact on the sound quality. Low-resistance audio cables can reduce signal loss during transmission and maintain the integrity and dynamic range of audio signals. In addition, the resistance of the audio cable must be kept stable to avoid the impact of resistance fluctuations on the sound quality caused by temperature changes and other factors‌1.

‌No shielding layer design‌: Compared with audio cables, audio cables often do not have a shielding layer. This design makes the audio cable simpler in design and manufacturing, while also reducing costs. The design without a shielding layer reduces the obstruction of signal transmission to a certain extent and is conducive to improving signal transmission efficiency and quality‌2.

To sum up, the audio cable ensures low loss and high fidelity during the transmission process of audio signals through its high-quality material selection, special design structure and excellent electrical performance, thus providing a high-quality audio experience‌
