Furutech CF63-S (R) 6.3 stereo to 3.5 Stereo Headphone Connector Adaptor (each)

Furutech CF63-S (R) Is a High-End Rhodium-Plated 6.3mm Headphone Connector for Audiophile-Grade Signal Transmission

Furutech CF63-S (R) is a precision-engineered 6.3mm (¼-inch) stereo headphone plug designed for uncompromising signal integrity and mechanical strength. Built with Furutech’s proprietary α (Alpha) phosphor bronze and copper alloy, this high-performance connector delivers superior conductivity, tonal purity, and long-term reliability for discerning audio professionals and dedicated hi-fi enthusiasts.

Main Conductor Uses α (Alpha) Phosphor Bronze for Ultra-Stable Signal Contact

The main conductor of the Furutech CF63-S (R) is Rhodium-plated α (Alpha) phosphor bronze and copper alloy, chosen for its low impedance and superb durability under repeated use. The rhodium plating enhances corrosion resistance while offering a smooth, extended high-frequency response, which is especially critical in professional studio environments or for premium headphone upgrades. This highly conductive base material ensures clean, lossless signal transfer with minimal distortion, catering to audio setups where signal fidelity is paramount.

Insulation Employs POM Resin for Rigidity and Dielectric Precision

Furutech insulates the CF63-S (R) with high-grade POM (Polyoxymethylene) resin, a material known for its structural stiffness and excellent dielectric characteristics. The insulation layer maintains the conductor’s stability while suppressing microphonic interference. This ensures that even the most subtle audio nuances are preserved during transmission, making it a premium connector for critical listening applications, including headphone amps, DACs, and mastering chains.

Housing Combines Carbon Fibre and Rhodium-Plated α Copper Alloy for Structural and Aesthetic Sophistication

The CF63-S (R) connector features a housing crafted from Rhodium-plated α (Alpha) copper alloy finished with carbon fibre, delivering both functional resilience and luxurious visual appeal. The use of carbon fibre not only adds a modern, high-tech finish but also contributes to vibration damping, reducing mechanical resonance. This construction is ideal for audiophile interconnects where physical stability and sonic purity must coexist seamlessly.

Size Offers Compact Form Factor for Precision Builds

The Furutech CF63-S (R) measures approximately 11.5mm in diameter by 61.0mm in length, offering a space-saving profile without sacrificing strength or ease of use. Its compact footprint supports use in precision cable builds and tight equipment layouts, particularly useful for high-end headphone cables, studio patch bays, or portable rigs where durability and clarity are critical.

Furutech’s CF63-S (R) sets a reference standard for rhodium-plated 6.3mm headphone connectors, delivering unrivalled performance in both professional and high-fidelity listening environments.
