Genuine Quality Materials
The copper materials used are authentic Furukawa products from Japan. These copper materials, renowned for their excellent acoustic performance, are an excellent choice for high-end audio applications.
Secondary Refining
This process removes impurities and further improves the purity of the monocrystalline copper, reducing distortions caused by crystal boundaries in the wires.
Wire Drawing
More than 70 steps of wire forging and drawing are performed to ensure the wires meet the highest quality standards, resulting in diameters as small as 0.05/0.8mm.
Unidirectional Welding
Crystalline unidirectional welding follows the direction of the crystal grains to reduce signal obstructions from the crystals.
Silver-containing Lead-free Solder
The LL-RC 2024 uses high-quality silver-containing lead-free solder to minimize signal loss and provide a fuller, more transparent sound.
LL-RC 2024 Sound Characteristics
The FiiO LL-RC 2024 uses secondary-refined Furukawa authentic monocrystalline copper materials, enhancing the sound of the headphones for a revitalized and clear audio experience.
Transparent Mids
The mids are made smoother and denser, offering more transparent and clean vocals, which are a vital part of music.
Robust Bass
Deeper, higher-quality bass makes the music come alive.
Enhanced Dynamics
The dynamic range is significantly enhanced while maintaining the original soundstage, making complex compositions like symphonies more enjoyable to listen to.
Optimized Overtones
The transient speeds are optimized, allowing subtle overtones to be more easily appreciated, providing a 3D feel to the audio.
Overall Clarity
Thanks to the careful craftsmanship and thoughtfully designed cable, the signal is transmitted more efficiently and without loss, especially at higher frequencies. The result is a clearer sound that brings the listener closer to the music, whether it's female vocals or orchestral compositions.
Genuine Furukawa Copper Material Imported from Japan
Behind excellent-sounding products are high-quality materials. The copper used in the LL-RC 2024 cable comes from Furukawa Denki Industrial Co., Ltd. in Japan, with official certification. You can trust the cable’s excellent sound quality due to its genuine materials.
Secondary-Refined Monocrystalline Copper
The copper wires in the LL-RC 2024 undergo extensive treatment to ensure excellent signal transmission performance. After treatment, pores, impurities, and grain boundaries in the copper are minimized, allowing signals to travel more freely through the wires and delivering excellent audio performance.
High-Standard Wire Drawing
The high-purity monocrystalline copper wires undergo more than 70 steps of drawing, forging, and other processes to transform oxygen-free copper with many impurities into high-purity monocrystalline copper wires with diameters of only 0.05mm, ensuring the best audio performance.
Large Number of 560 Wires
In audio cables, more wires mean a larger cross-sectional area, which reduces resistance and improves conductivity. The FiiO LL-RC 2024 contains 560 wires across 4 strands, with a total diameter of 21AWG. This distinguishes the cable from others, as cables this thick and filled with high-quality wires are uncommon.
Maximizing the Potential of Excellent Materials Coaxial Braided Wires
To fully maximize the potential of the 560 wires, the wires inside the LL-RC 2024 follow a coaxial braiding structure. The 0.05mm diameter copper wires are used for the inner layer of wires. Every 25 of these wires are braided into one smaller strand, and 8 of these smaller strands are braided together to form a larger strand. These larger strands serve as a positive signal for improved signal transmission efficiency. The 0.08mm diameter copper wires are used for the outer layer of the wires, acting as a shield to isolate the inner wires from interference.
Audible High Quality Refined Tuning from the Coaxial Braided Structure
Every aspect of the cable was carefully considered to maximize sound quality, and the braiding method of the inner wires is no exception. Smaller diameter wires are softer, with a 0.05mm diameter being the minimum required to maintain crystal integrity. Larger diameter wires have lower resistance, enabling better signal flow. After conducting numerous tests on the ideal wire diameter for audio signals, it was determined that combining 0.05mm and 0.08mm diameter wires braided together was the best option for audio performance—resulting in lusher mids and clean, transparent vocals that allow the listener to truly appreciate the soul of the music.
The Invisible Hand Behind "Good Sound" Silver-containing Lead-free Solder
The high-quality nature of the LL-RC 2024 extends to components not immediately visible, such as the solder used. The LL-RC 2024 employs high-quality silver-containing lead-free solder, allowing signals to flow smoothly through the wires with minimal loss. The result is a more transparent and fuller sound, taking your listening experience to the next level.
Every Last Detail Considered Crystalline Unidirectional Welding
FiiO, with 17 years of experience in the audio industry, is renowned for its attention to detail. As the crystal grains of monocrystalline copper have directional properties, the cable is made using unidirectional welding that follows the direction of the crystal grains. This ensures that signals flow freely along the wires and maintains consistency in the cable's sound.
Long-lasting, Reliable Tool High-quality Braided Nylon Protective Sheath
The outer protective sheath of the LL-RC 2024 is made from high-quality braided nylon. This material is flexible yet durable, able to withstand bending and rolling, ensuring long-lasting use of the cable.
3.5mm Single-ended/4.4mm Balanced Swappable Plugs
The FiiO LL-RC 2024 comes standard with swappable 3.5mm single-ended and 4.4mm balanced plugs, allowing you to easily switch plugs depending on the device you're connecting to.
*Interchangeable audio plugs are officially licensed from the FABRILOUS patent.
