The FiiO LL-RC2025 headphone cable is a premium 1.5m audiophile cable made from 6N monocrystalline copper and Furukawa copper conductors. Featuring 176 wires in a 21AWG coaxial braided structure, –192°C cryogenic treatment, and swappable 3.5mm & 4.4mm connectors, the cable delivers high conductivity, reduced distortion and superior signal transmission for high-end headphones.
FiiO LL-RC2025 Cryogenic Monocrystalline Copper Headphone Cable
The FiiO LL-RC2025 Cryogenic Monocrystalline Copper Headphone Cable is a high-performance audiophile cable engineered to deliver exceptional signal purity, durability and compatibility with modern audio devices. Designed as an upgraded 1.5-meter headphone cable, the FiiO LL-RC2025 headphone cable addresses the portability limitations of longer stock cables while maintaining uncompromised audio quality.
At the core of the FiiO LL-RC2025 headphone cable are carefully selected 6N monocrystalline copper conductors combined with high-purity Furukawa copper wires sourced from Japan, ensuring extremely high conductivity and excellent signal transmission. The cable features a total of 176 precision wires arranged in a 4-strand coaxial braided structure with a 21AWG diameter, significantly reducing transmission loss while improving resistance to interference.
To further enhance performance, the FiiO LL-RC2025 headphone cable undergoes a –192°C cryogenic liquid nitrogen treatment, which reduces internal stress within the copper material and optimizes its molecular structure. This process improves conductivity and ensures a smoother and more natural audio signal path. Combined with a low-dielectric PFA insulation layer, the cable maintains excellent high-resolution performance while achieving balanced tonal characteristics.
The advanced design of the FiiO LL-RC2025 headphone cable also incorporates crystalline one-way welding technology, ensuring signal transmission follows the natural direction of the copper crystal grains for maximum efficiency. High-quality silver-containing lead-free solder further minimizes signal loss and enhances overall transparency and detail retrieval.
For improved versatility, the FiiO LL-RC2025 headphone cable features swappable plugs including both 3.5mm single-ended and 4.4mm balanced connectors, allowing users to easily adapt the cable to different audio players, DAC/AMP devices and headphone systems. The connectors and middle structure are constructed using aluminum alloy and carbon fiber components, providing durability while maintaining a lightweight and premium design.
With its combination of high-purity copper conductors, cryogenic treatment, precision braiding and swappable balanced connectors, the FiiO LL-RC2025 headphone cable represents a premium upgrade for audiophiles seeking improved signal integrity, reduced distortion and a more transparent listening experience.
