Hidizs BL4.4A-RC+Mermaid MD4 HiFi In-Ear Monitor Earphones Bundle

The HIDIZS BL4.4A-RC balanced earphone upgrade cable is mixed with 2 single-crystal copper-plated silver wires to improve signal transmission efficiency. According to Lenz's law "the effect of the induced current always resists the cause of it", when the current passes through the conductor, it is easy to form a high-density current on the surface of the conductor, which hinders the signal transmission effect of the conductor. Therefore, the surface of the conductor can be effectively relieved by silver plating. Distributes pressure, and improves conductivity and stability. At the same time, silver-containing solder is used at the connection point to ensure signal transmission efficiency.

HIDIZS BL4.4A-RC balanced earphone upgrade cable combines the advantages of single-crystal copper and silver-plated single-crystal copper to achieve stable and rapid transmission. The power has been improved, the resolution is excellent, the atmosphere is better, and the sound is natural and delicate, warm and mellow.

The HIDIZS BL4.4A-RC balanced earphone upgrade cable adopts a standard 0.78mm 2pin interface. Compared with the 0.75mm standard, the contact area is larger and more stable, and it is not easy to bend. It improves the stability of transmission and is more durable. The size of the positive and negative double pins of 0.78mm 2-pin is exactly the same, which can be adapted to most of the flat female base earphones on the market and all HIDIZS brand earphones.
