Furutech CF-7445(R) High End Performance 4.4mm (TRRRS) Connector (each)

Furutech CF-7445(R) Delivers Audiophile-Grade Balanced Audio Transmission

Furutech CF-7445(R) is a high-end 4.4mm TRRRS balanced headphone connector engineered for uncompromised sound integrity and mechanical stability. Designed specifically for demanding applications such as the Sony Signature Series (NW-WM1Z, NW-WM1A, TA-ZH1ES), this connector blends precision craftsmanship with performance-driven material science, making it a standout choice for custom headphone cables, portable DACs, and professional-grade portable audio systems.

CF-7445(R) Features Precision-Machined One-Piece Rhodium-Plated α (Alpha) Copper Alloy

The connector’s core is its one-piece signal conductor, made from rhodium-plated α (Alpha) Copper Alloy. This single-piece design ensures seamless current flow and reduces the distortion and signal degradation often introduced by multi-part terminations. The rhodium plating adds exceptional resistance to corrosion and wear, improving longevity in high-use environments and preserving contact integrity over time. This direct-signal-path design caters especially to audiophiles seeking the purest possible reproduction of high-resolution audio files, including DSD and Hi-Res PCM formats.

CF-7445(R) Optimises Signal Stability with Audio-Grade POM Insulation

Insulation in the Furutech CF-7445(R) uses high-specification audio-grade POM (Polyoxymethylene), chosen for its low dielectric constant and superior mechanical properties. This minimises capacitive interaction between conductors and ensures that signal stability remains consistent under all load conditions. POM’s stiffness further supports cable alignment inside the plug, which is critical in maintaining channel separation and reducing crosstalk in balanced audio configurations—especially across the Left+, Left−, Right+, Right−, and ground terminals in 4.4mm TRRRS applications.

CF-7445(R) Integrates Stainless and Carbon Fibre Housing for Vibration Control

A signature aspect of the CF-7445(R) connector is its elegantly engineered outer housing, crafted from stainless steel and layered with a carbon fibre shell. This hybrid structure isn’t just cosmetic—carbon fibre’s resonance-damping qualities work in tandem with the rigid stainless body to suppress microvibrations and mechanical noise transmission, preserving audio clarity. The result is tighter bass, more accurate imaging, and greater low-level detail retrieval—benefits easily perceivable with premium IEMs and planar magnetic headphones.

CF-7445(R) Supports Thick Cable Builds with Secure Copper Alloy Clamp

To accommodate audiophile-grade cable builds, the Furutech CF-7445(R) includes a high-tension copper alloy cable clamp that accepts core insulation diameters up to 6.0mm. This supports thicker, multi-strand, or shielded conductors commonly used in hand-built cables for mobile and desktop rigs. The clamp design ensures secure mechanical anchoring, preventing rotation or dislodgement under strain, and further isolates signal paths from external movement—an essential feature when used in portable headphone setups.

CF-7445(R) Enables Easy Soldering with Optimised Contact Surfaces

Designed for professional builders and hobbyist audiophiles, the solderable contacts on the CF-7445(R) are pre-plated with rhodium but may require light surface abrasion prior to soldering. This ensures reliable wetting and joint integrity during installation. The internal layout clearly separates the five terminals (Tip, Ring1, Ring2, Ring3, Sleeve) used in TRRRS configurations, streamlining assembly for balanced headphone or line-level output use cases.

CF-7445(R) Is Purpose-Built for Sony Signature Series and Balanced Audio Devices

Engineered with precise tolerances and a connector profile tailored for Sony’s Signature Series products, the CF-7445(R) integrates seamlessly with devices like the NW-WM1Z, NW-WM1A, and TA-ZH1ES. This makes it the go-to choice for users upgrading stock cables or building bespoke headphone terminations for premium balanced outputs. Its fit ensures secure mating without signal dropouts or loose contact—essential for portable listening on the move or studio-quality playback.

CF-7445(R) Combines Boutique Craftsmanship and Furutech’s Signature OEM Quality

Furutech CF-7445(R) represents the brand’s ethos of zero-compromise connectivity. Known globally for their OEM-grade parts, Furutech incorporates decades of signal path research into every design element, no matter how minute. Each connector reflects extensive auditioning, advanced metallurgy, and a commitment to sonic neutrality—ensuring users experience music exactly as recorded, with no coloration or signal loss.

Whether you're building high-end headphone cables, upgrading interconnects for a portable amp stack, or constructing balanced adapters for DAPs and DAC/Amps, the Furutech CF-7445(R) offers a reference-grade termination option that matches the precision and aesthetic demanded by audiophile and professional audio enthusiasts alike.
