Filter Zone
Extensive Testing
After many studies and tests, we chose stainless steel for the filling zone - its acoustic stability and the synergy of the Venturi shape provide clearer highs, less distortion and a more refined listening experience
Special Texture Design: Real shot 6x magnification
Pressure Release Grip System
The unique pattern designed on the earplugs serves a dual purpose: pressure relief and a secure, comfortable fit
Variable Aperture:
The Venturi-shaped hole transmits sound by narrowing and then expanding the airflow path, which controls pressure and speed, reduces turbulence
and enhances the way sound waves travel to the ear. This can improve clarity, focus and frequency balance, especially in the high-pitched area
and mid-range.
Premium Liquid Silicone
The medical-grade hypoallergenic material is made of high-quality silicone, which exceeds medical-grade standards for better comfort and safety. The grip and long-lasting durability are also perfect for long-term listening. It is skin-friendly and comfortable to wear without irritation.
Medical Laboratory Certificate
Soft touch. Happiness in the ears, even forget it's there
Optimized core body design
Designed with a shorter core to optimize sonic clarity and responsiveness, yet still retaining a thicker core to resist deformation and increase durability.
