THE MOMENT TO MOVE UP

Your next IEM should not
sound like more of the same.

A better IEM should not simply expose more detail. It should bring greater control, space and realism to everything you already love.

PERSEUS is for listeners ready to move beyond incremental upgrades: resolution you can appreciate immediately, with the tonal body and ease to enjoy for hours.

A COMPLETE EFFECT AUDIO SYSTEM

PERSEUS marks the entry point into Effect Audio’s complete acoustic system, bringing together our expertise in both IEM and cable design. Developed as a unified package, every element — from its quad-brid driver architecture to its dedicated ORDINIS cable and full-metal housing — has been carefully selected and tuned to work as one coherent system.

Its design takes inspiration from the Harpe, the divine blade carried by Perseus in Greek mythology. The multi-angled aluminum faceplate carries that sense of precision into its form, while the rigid metal chamber provides a stable acoustic foundation for the 9-driver system within.

Together, the acoustic architecture, ORDINIS cable, and aluminum housing help PERSEUS deliver bass control, spatial definition, clean detail, and an effortless sense of musicality from the very first listen.

Effortless Power: 9-Driver System

ACOUSTIC TECHNOLOGY

INSIDE PERSEUS

A complete acoustic system built around driver synergy, controlled tuning, and effortless everyday performance.

KINETIC² ISOBARIC DYNAMIC DRIVERS

PERSEUS features a dual isobaric push-pull dynamic driver chamber, designed to maximise efficiency within the acoustic system. It allows the bass to extend deeper with greater authority, delivering weight and impact without sacrificing precision.

CUSTOMIZED SONION 2300 BALANCED ARMATURES

PERSEUS uses customized Sonion 2300 balanced armatures selected for tonal character and adaptability within a controlled acoustic system. Each unit is integrated with the crossover and cable architecture to shape a midrange with clarity, density, and emotional expression.

ISOPLANAR QUAD SYSTEM

PERSEUS uses four new-age micro planar drivers instead of ESTs or traditional balanced armatures. By distributing the workload across ultra-light diaphragms, treble reproduction becomes cleaner, more resolving, and effortlessly extended.

PTZ Bone CONDUCTION DRIVER

A PTZ bone conduction driver works with PERSEUS’ rigid aluminum housing to reinforce spatial definition and presence. By using the metal chamber as a stable acoustic foundation, it helps preserve vibration energy, strengthen imaging cues, and create a more natural sense of dimension.

ORDINIS CUSTOM CABLE

CABLE MATERIAL ARCHITECTURE

Developed specifically for PERSEUS, ORDINIS combines multiple conductor materials to support tonal balance, speed, vocal texture, and controlled detail retrieval.

EA GEOMETRIC COPPER CONDUCTORS

Adds warmth and body while controlling the excess bloom often associated with traditional copper designs.

GOLD-PLATED SILVER

A flagship material within Effect Audio’s lineage, selected to enhance vocal density, harmonic richness, and smoother upper-mid expression.

CUSTOM SILVER-COPPER ALLOY

Balances conductivity and tonal weight, helping maintain body, resolution, and stable detail retrieval without sounding overly sharp.

UP-OCC PURE SILVER

Preserves speed, openness, and high-resolution clarity, supporting treble extension and micro-detail reproduction.
