From the brand
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.
Â
Perseus introduces our first quad-bird driver architecture, integrating dual dynamic drivers, dual balanced armatures, four micro planar drivers, and a bone conduction unit into a single, cohesive system. The system is engineered for high efficiency, allowing it to be driven with ease across a wide range of portable sources without loss of control or dynamic capability.
Neutral at its core. Alive in every detail. PERSEUS reveals detail through control, coherence and spatial precision—not exaggerated brightness. Bass: Deep extension with firm control and textured impact. Midrange: Natural note weight with clear, expressive vocals. Treble: Clean extension and fine detail without excessive brightness. Imaging: Precise placement with strong separation and layered depth.
PERSEUS comes complete with its purpose-developed ORDINIS cable, two eartip options and a premium leather carrying case. Choose ARC Oval for more upper-mid and treble presence with vocals brought closer, or Symbio F for an alternative fit and seal.
