Effect Audio

Effect Audio is a Singapore-based manufacturer of premium headphone upgrade cables.

Specializing in the design and production of high-end replacement cables for in-ear monitors (IEMs), the company was founded in 2009 by Zou Suyang. Since its inception, Effect Audio has evolved from a small online business into a global industry leader, providing professionals and audiophiles with a unique listening experience through meticulously engineered products.

The brand gained significant international acclaim with the launch of its Signature Series, which featured three iconic models: the Ares S, Cadmus, and Eros S. Following the widespread success and critical praise of this lineup, Effect Audio conducted extensive research and development to push the boundaries of performance even further.

The culmination of these efforts is the second generation—the Signature Series II. Like its predecessor, the lineup consists of three models: the Ares S II, Cadmus II, and Eros S II. Each cable in the Signature Series II incorporates advanced technologies, such as the Solid-Core design previously found in the brand's flagship Code and Fusion series.

These are the world’s first eight-core cables to feature both a Solid-Core design and an 8-Wire Handwoven structure. They also debut a new Y-Splitter geometry, resulting in cables that are not only more sonically capable but also lighter and more ergonomic than the original series.
