7Hz / 7 Hertz ELUA Ultra

Ergonomic Comfort

7Hz Elua Ultra polishes each earbud to exact tolerances for a snug, fatigue-free fit, delivering stability and all-day comfort.

Precision Dual Drivers

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

Advanced LCP Composite Diaphragms

It employs a three-layer LCP composite diaphragm assembly—combining an LCP dome with a soft suspension ring—to minimize resonance. Iterative tuning by expert engineers yields smooth bass, clear mids, and crystalline highs.

Premium Detachable Cable

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

HARMAN Target Curve Tuning

Its measured frequency response is harmonized to the HARMAN target curve, offering a natural soundstage with ultra-low distortion—perfect for gamers and music enthusiasts seeking balanced, engaging performance.
