Headphone Cables

The Last Cable Your Music Touches

The headphone cable is the final transmission line between amplifier and transducer. Everything the electromagnetic field has accumulated across your system — every noise interaction, every boundary distortion, every RF coupling — is delivered to the driver through this cable. That's why we engineer our headphone cables as field-optimized waveguides, not just conductors. Geometry, dielectric, shielding, and active tuning structures work together to control how energy reaches your ears, preserving the low-level timing and spatial information that creates a truly holographic, out-of-your-head soundstage.

Our SRX XL Headphone Cable represents the pinnacle of this approach, featuring 99.9995% Pure Silver Air String conductor geometries, SRX XL Matrix Shielding with our most advanced UEF compound, High Voltage Conditioning at 1,000,000 volts, and Gold and Master carbon fiber UEF Tuning Modules for system voicing. Foundation XL Headphone Cables bring the same SRX XL shielding and conditioning with doubled Pure Silver Air Strings at an accessible price point, and offer the broadest headphone connector compatibility in our lineup — supporting Sennheiser, Audeze, Focal, Hifiman, Dan Clark Audio, ZMF, Meze, and more. Both cables are 100% hand-crafted in our California factory, and the difference they make is not subtle. Trust your ears. That's always been the best test.
