Precision Dual Drivers

Elua equips the Ultra with two custom dynamic drivers—10 mm and 8 mm—featuring LCP composite diaphragms with flexible surrounds, N52 magnets, and Japanese large-diameter voice coils for low distortion, high resolution, and an expansive frequency range.

Advanced LCP Composite Diaphragms

Elua engineers a three-layer LCP composite diaphragm assembly—combining an LCP dome with a soft suspension ring—to minimize resonance. Expert tuning through iterative testing yields smooth bass, clear mids, and crystalline highs.

Premium Detachable Cable

Elua includes a 0.78 mm 2-pin OCC copper cable that boosts channel separation and precision for pristine detail in vocals and instruments. Its durable dual-pin connector ensures long-term reliability, and the detachable design lets you upgrade cables as desired.

Target Curve Tuning

Elua Ultra’s measured frequency response is harmonized to the target curve, offering a natural soundstage with ultra-low distortion. Perfect for gamers and music enthusiasts seeking balanced, engaging performance.
