Leonidas Z
Leonidas Z is the first model in EFFECT AUDIO’s new Chronicles of Legends series — a line created to revive our most iconic designs.
As the continuation of the Leonidas lineage, Leonidas Z represents EA’s heritage: classic tonal philosophy rebuilt with updated materials, structure, and craftsmanship.
*Both 4W and 8W models comes with ConX® Full Set & Pentaconn OFC 4.4mm Termination, and every Leonidas Z is accompanied by a hand-crafted calfskin carrying case.

A Masterful Composition
At the heart of Leonidas Z lies UP-OCC Pure Silver with Central Solid-Core, a continuous conductor design that eliminates the gaps found in traditional multi-stranded builds. This ensures purer signal flow, lower resistance, and greater stability across the frequency range, which explains why this cable can so profoundly influence sound. The result is uncompromising clarity and speed, with added air and definition.
Layered onto this core is UP-OCC Gold-Plated Silver, enriching the mid and upper-midrange with warmth, body, and a natural sweetness in vocals. Completing the composition is UP-OCC Palladium-Silver Alloy, which refines the upper treble with remarkable finesse, expands imaging precision, and opens up the soundstage. It is especially effective in awakening overly warm IEMs, yet versatile enough to avoid pushing them over the edge.
Together, these elements give Leonidas Z not only sparkle but also stronger bass pressure, more natural decay, and a balanced, resolving tonality that marries technicality with musicality

Within the Chronicles of Legends, every chapter carries a name and the character it represents, written into EFFECT AUDIO’s history through craft and sound. Among them, Leonidas has long been loved by audiophiles for a balance of refinement and authority that made him an icon of the series.
With Leonidas Z, that legacy moves forward. Built from the noble metals that shape our greatest works, and designed with a structure that delivers scale and precision in equal measure. While Centurion II achieves its summit with Platinum-Silver Alloy, Leonidas Z channels a vision of scale and refinement through Palladium-Silver Alloy.
Now, this icon is reborn. Carrying the legacy of his line yet speaking with a new presence, Leonidas Z stands as a true reawakening of the legend.



The Sound of Legacy
Leonidas Z redefines what a silver design can achieve. Where many cables of this blend tend to sound overly bright, lean, or mid-forward, Leonidas Z strikes a truer balance. Its darker, quieter background allows micro-details to emerge without glare, while its treble extends with finesse, giving instruments sharper imaging and a more expansive sound field.
The midrange carries emotional weight without exaggeration, avoiding the W-shaped emphasis that can pull focus away from musical coherence. What emerges is an organic yet vivid presentation — open and airy, but never fatiguing; powerful and textured, yet always musical. Leonidas Z does not merely add sparkle, it completes the spectrum, creating a stage that feels immersive, commanding, and unmistakably its own.
Crafted Experience
The Y-split of Leonidas Z is wrapped in calfskin leather, a material valued for its fine grain and natural resilience. Across its surface, the name “Leonidas Z” is laser-engraved, leaving a permanent mark that binds the design to its identity. The contrast of cool metal and warm leather makes it strong in build, yet timeless in appeal.
Each piece is stitched by artisans, giving the Y-split a quiet expression of craft and a touch only hand stitching can impart. Every Leonidas Z comes with a dedicated carrying case crafted from the same calfskin, protecting your cable in a way that feels as considered and refined as the cable itself.
