SOVEREIGN

The crown first rests upon a composed ruler. With each passing season, his reign earns ever greater distinction. His authority reaches beyond the furthest frontier. His legacy endures beyond the measure of time. At the zenith of his reign, imperial robes unfold. Molten gold follows his stride. The sceptre settles with certainty in his grasp. The Emperor reveals his highest form: SOVEREIGN - The One Above All. EFFECT AUDIO and qdc unite to create SOVEREIGN—an ultra-flagship IEM born from an award-winning acoustic lineage and elevated through newly developed tuning, custom internal wiring and the exclusively created IMPERIAL SCEPTRE cable. SOVEREIGN builds upon the foundation of qdc EMPEROR—recipient of three consecutive VGP Gold Awards from 2024 to 2026, alongside the 2024 EHA HiFi Audio Gold Award and Technology Innovation Award. Following GMA FE in 2025, SOVEREIGN marks EFFECT AUDIO's next flagship IEM collaboration. Limited to 200 units worldwide. *Stocks are expected to ship from the mid of November. **This release is a global launch (excluding China).
