FiiO LINK-RCA4 3.5mm to RCA Digital Audio Coaxial Cable

The FiiO LINK-RCA4 is a premium 3.5mm to RCA digital audio coaxial cable designed for clean, reliable connection between compatible audio devices.

The LINK series is FiiO’s upgraded cable range, created for listeners who want a more refined cable than a basic everyday option. The name “LINK” represents the connection between audio components, and the deeper connection between music and the listener. Compared with FiiO’s entry-level TRUST series, LINK cables are designed as a more advanced choice, using higher-grade materials, stronger shielding and a more premium finish.

Inside, the LINK-RCA4 uses high-purity silver-plated monocrystalline copper conductors, paired with dual-layer shielding made from graphene-coated aluminium foil and tinned copper. This helps support stable signal transfer while keeping the cable flexible and practical for everyday audio use.

The plug housings are CNC-machined from anodised aluminium alloy for improved wear and corrosion resistance, with FiiO’s signature Arc design making the cable easier to grip, plug in and remove. The cable also uses a flame-retardant PVC sheath, glossy polyester FDY braided outer layer and reinforced core wire with 500D high-strength nylon filament for improved pull and swing resistance.

Finished with a subtle multi-colour braided design in gold, silver and green, the FiiO LINK-RCA4 offers a tidy, durable and premium-feeling cable.
