Furutech FT-735SM (R) Stereo Connector

Furutech FT-735SM (R) Integrates One-Piece α Alpha Conductor Precision

Furutech FT-735SM (R) 3.5mm stereo connector is a high-fidelity component built for discerning audio professionals, custom cable makers, and performance-focused enthusiasts who prioritise signal clarity in compact form factors. Developed with Furutech’s signature engineering precision, the FT-735SM (R) delivers superior transmission quality through its unique one-piece α (Alpha) pure copper conductor, housed in an acoustically inert stainless steel body.

FT-735SM (R) Maximises Signal Integrity with Monoblock α Alpha Pure Copper

FT-735SM (R) features a single-piece α Alpha pure copper conductor, meticulously machined to ensure seamless signal flow without impedance discontinuities. This monoblock architecture avoids the resistive flaws of multi-part plugs, maintaining phase accuracy and tonal integrity. Rhodium plating adds a protective, high-conductivity layer that resists oxidation, ensuring long-term signal stability under high usage cycles common in portable and studio gear.

Furutech Connector Design Reduces Noise and Enhances Electrical Performance

FT-735SM (R) integrates a rhodium-plated α Alpha copper alloy ground conductor, forming a perfectly matched signal return path. This low-resistance architecture is engineered to reject EMI/RFI interference, providing a dark, quiet background for audio playback. The high-tensile stainless steel housing offers robust physical protection while minimising vibration transmission that could degrade contact consistency during operation.

Specialised Insulation Material Stabilises Dielectric Performance

FT-735SM (R) employs a nylon glass fibre resin insulator, engineered to maintain dielectric stability and mechanical form under repeated thermal and mechanical stress. This material was selected specifically for its ability to preserve signal purity at high frequencies, reduce capacitive coupling, and prevent signal phase smear. Its structural integrity also aids in maintaining internal alignment between tip, ring, and sleeve for precise stereo imaging.

Compact Dimensions Enable Integration in High-Performance Builds

FT-735SM (R) measures 43.0mm in total length, with a housing diameter of 10.0mm and a shell length of 25.0mm, making it suitable for both mobile audio and high-density rack or desktop configurations. These space-conscious dimensions enable integration into compact chassis or tightly routed custom cables without compromising structural stability. The plug accommodates cables with core insulation diameters up to 5.0mm, making it compatible with a wide variety of high-end and aftermarket cable builds.

Durable Construction Supports Soldered Termination for Long-Term Use

FT-735SM (R) uses soldered connections, which provide a more stable and electrically secure joint than crimp or snap-fit alternatives. The internal copper alloy cable clamp maintains a firm grip on the conductor without introducing mechanical stress, preserving strand integrity. This construction supports both ruggedised mobile use and audiophile-grade home setups where repeatable, reliable connections are critical.

Furutech’s FT-735SM (R) sets a new benchmark for 3.5mm stereo connectors by combining one-piece conductor innovation, advanced materials, and precision-machined construction in a compact yet robust profile. Ideal for upgrading headphone cables, interconnects, or portable audio devices, this connector exemplifies performance without compromise.
