Description

The Effect Audio introduced the Signature Series II, a much-anticipated launch that marks two years since the original series set new industry standards. The Effect Audio Signature Series II Eros S II 8-Wire Earphone Cable features a multi-material Litz construction, combining silver and copper alloy, pure silver, and pure copper in a hybrid design. It incorporates a silver central solid core and six multi-sized core bundles, utilizing the proprietary Tri-Element synCompound (TESC™) technology. The cable is crafted with 26 AWG 8 wires and insulated with EA Ultra Flexi™ material for enhanced flexibility. It comes equipped with a ConX® 2-pin connector and an EA standard rhodium-plated brass straight-type plug.

Rooted in the wisdom of the Classics, where greatness first took flight, we push forward to create a legacy that reaches even greater heights. Like Ares, Cadmus, and Eros—heroes whose stories evolved through time—we honour tradition while embracing change. With innovation as our guide, we craft solutions that combine better ergonomics, advanced materials, and visionary designs. Our path is clear. Our mission is bold. The next chapter begins here.

PREMIUM UP-OCC SILVER-PLATED COPPER LITZ CABLE

Built with UP-OCC pure silver and a central solid core design, the Eros S II introduces the advanced Solid Core Technology from the CODE Series. This design replaces multi-stranded conductors with a single, seamless wire, ensuring lower resistance and minimal signal loss at high frequencies, delivering a cleaner and more consistent audio experience.

MODULAR DESIGN WITH CONX CONNECTORS

The Eros S II features ConX connectors on the IEM side. This modular design allows you to easily switch between different connector types (MMCX, P
entaconn Ear, IPX, A2DC) by purchasing optional ConX adapters, expanding the cable's compatibility with a wide range of IEMs. The source side terminates in a standard Rhodium-plated brass 4.4mm straight plug.
