Hybrid Design for Exceptional Sound

The Eclipse 500 is ACS’s first hybrid universal IEM, combining the rich, punchy low-end of a dynamic driver with the stunning detail and accuracy of balanced armature drivers. The result? A beautifully tuned sound signature featuring warm bass, clean mids, and sparkling highs with Hi-Res Audio certified extension.

Advanced Ambient Filter Technology

ACS’s innovative passive-ambient 17dB filter delivers natural sound isolation while allowing airflow in and out of the ear. This prevents the “plugged” feeling common with IEMs, reduces listening fatigue, and opens up the soundstage for an immersive, spacious experience that's perfect for long sessions on stage or on the go.
