Description

Premium copper and one-way welding

The LL-RC pairs 6N monocrystalline copper with high-purity Furukawa-certified copper. A crystalline one-way welding process aligns the joints with the natural direction of the copper grain, and silver-containing lead-free solder keeps resistance low at the connection points. The result is a transparent, full-bodied sound with strong tonal balance.

Cryogenic treatment and coaxial braid

The conductors go through a -192 °C liquid-nitrogen cryogenic treatment that releases internal mechanical stress in the copper, preserving the high resolution of the monocrystalline structure. 176 wires distributed across four strands give a 21 AWG total gauge. The coaxial braided architecture distributes high-frequency current evenly across the conductor surface to mitigate skin effect, and a low-dielectric PFA insulation layer rejects external interference and high-frequency noise.

Swappable plugs, premium build

A swappable plug system lets you switch between the included 3.5 mm single-ended and 4.4 mm balanced terminations to match your source. The middle and plug housings combine aluminum alloy with carbon fiber accents, and the cable is offered in 1.5 m and 3.0 m lengths to fit both portable and home setups.

Common Questions

Why choose the FiiO LL-RC headphone cable?

For high-end headphones like the FiiO FT7, this is a portable upgrade cable with both balanced and single-ended terminations in the box — no compromise in sound quality between sources.

What are the benefits of the -192 °C cryogenic treatment?

The liquid-nitrogen treatment relieves internal mechanical stress in the copper, which preserves resolution and delivers a more balanced sound than untreated copper.

Does this cable support balanced audio connections?

Yes, a 4.4 mm balanced plug is included alongside the 3.5 mm single-ended plug.

What is the purpose of the coaxial braided structure?

It distributes high-frequency current evenly across the conductor surface, reducing skin-effect losses and isolating the signal from high-frequency noise.
