What are The Advantages of The Fiio Furukawa Monocrystalline Copper Headphone Cable?

A high-end headphone cable should be high-quality in all aspects. Compared to the typical headphone cable, the FiiO LL RC 2024 contains not only high-quality materials, but also has gone through careful design considerations regarding material processing, build quality, and ergonomics informed by our seventeen years of acoustic design experience - ensuring the cable fully unleashes the potential of your headphones.

LL-RC 2024 Sound Characteristics

The FIIO LL-RC 2024 uses secondary-refined Furukawa authentic monocrystalline copper materials, which enhances the sound of the headphones for a revitalized and clear sound.

Transparent Mids

Helps to make mids smoother and denser for more transparent and clean vocals, which are a key part of music.

Robust Bass

More and better quality bass, making music more lively.

Enhanced Dynamics

Significantly enhanced dynamic range while maintaining the original soundstage, making large-scale productions such as symphonies more pleasant to listen to.

Optimized Overtones

Optimizes transient speeds, allowing you to more easily appreciate subtle overtones for a more 3D feel to your audio.

Overall Clarity

Thanks to the careful craftsmanship and the thoughtfully designed cable, signal is transmitted more efficiently and without loss, especially those of higher frequencies. The result is a clearer sound that lets the listener get closer to the music, no matter if listening to female vocals or orchestral music.

Secondary-Refined Monocrystalline Copper

The copper wires in the LL-RC 2024 undergo through extensive treatment in order to ensure excellent signal transmission performance through the wires. After undergoing the treatment pores, impurities and grain boundaries in the copper are minimized - allowing signals to travel more unimpeded through the wires, giving the LL-RC 2024 excellent audio performance.

• 1050°C: Continuous heating for 48 hours to reach melting point.Melting raw materials into liquid
• 744 hours: Constant temperature sintering maintained for a long time.Fully allows impurities to sink to the bottom of the furnace
• Over 70 Complex Processes: Secondary increase in purity, Enjoy truly high-purity monocrys-talline copper

High-Standard Wire Drawing

The high-purity monocrystalline copper wires undergo through more than 70 steps of wire drawing, forging, and other processes to transform oxygen-free copper with high number of impurities to a high-purity monocrystalline copper wires with diameters of only 0.05mm, for the highest audio performance.

Ample Amount 560 Wires

For audio cables, more wires mean a larger cross-sectional area, which in turn means lower resistance and thus better conductivity. Within the Fiio LL-RC 2024 are 560 wires across 4 strands, with a total diameter of 21AWG. This sets the cable apart from others, as a cable this thick and full of high-quality wires is not commonly seen.

Making The Most out of Excellent Ingredients Coaxial Braided Wires

In order to fully maximize the potential of the 560 total wires, the wires inside the LL-RC 2024 following a coaxial braiding structure. The 0.05mm diameter copper wires are used on the inner layer of wires. Every 25 of these wires are braided into one smaller strand, and 8 of these smaller strands totaling 200 wires are braided into one larger strand - these larger strands act as a positive signal for improved signal transmission efficiency. The 0.08mm diameter copper wires are used on the outer layer of wires, acting as a shield to isolate the inner wires from interference.

Audible High Quality Refined Tuning from The Coaxial Braided Structure

All aspects of the cable were carefully considered with the purpose of maximizing sound quality, and the way the inner wires are braided are no exception. Smaller diameter wires are softer, with a 0.05mm dimeter being the minimum size necessary to ensure crystal integrity. Larger diameter wires feature lower resistance thus allowing improved signal flow through the wires. After conducting many tests on the ideal wire diameter for audio signals, it was determined that a 0.05mm and 0.08mm diameter wires braided together were the best for audio performance - for lusher mids as well as clean and transparent vocals that truly lets the listener appreciate the soul of their music.

The Invisible Hand Behind "Good Sound" Silver-Containing Lead-Free Solder

The high-quality nature of the LL-RC 2024 extends to aspects that are not immediately visible, such as the solder used. The LL-RC 2024 employs high-quality silver-containing lead-free solder, which allows signals to flow smoothly through the wires with minimal losses. The result is a more transparent and fuller sound, taking ur listening experience to the next level.

Every Last Detail Considered Crystalline One-Way Welding

FiiO has been in the audio business for seventeen years, and is renowned for their attention to detail. Since high-purity monocrystalline copper grains do have directional characteristics, the cable is made using one-way welding which follows the direction of the crystal grains. This allows signals to flow unimpeded along the wires and ensures consistency in the sound of the cable.

Staying with you for a Long Time, A Dependable Tool High-Quality Braided Nylon Protective Sheath

The protective outer sheath of the LL-RC 2024 is made of high-quality braided nylon. This material is flexible yet durable, more than capable of taking bending and rolling - ensuring you can listen using this cable for a long time.

Two Cable Lengths

The LL-RC 2024 is available either as a 1.5m long or a 3m long cable. The 3m version is suitable for uses cases that require a longer cable, such as for particular listeners, for gaming, or for professional recording studios. The shorter 1.5m version allows for easier storage and is more convenient for daily usage, as well as being more flexible. Both versions come with Velcro cable ties to allow users to easily manage the cable.

3.5mm Single-Ended/4.4mm Balanced Swappable Plugs

The FiiO LL-RC 2024 comes standard with 3.5mm single-ended and 4.4mm balanced swappable plugs, allowing you to easily switch plugs based on the device you are connecting to.
