1. 2x 10mm Beryllium-plated Dynamic Drivers + Knowles Mid-High BA + Knowles Ultra-High BA
The 10mm Beryllium-plated diaphragm leverages the unique properties of fiber diaphragm materials to deliver deep, impactful bass that remains tight and responsive (no "muddiness"), providing an immersive listening experience. This is paired with a Knowles mid-high unit and a Knowles ultra-high unit to precisely resolve every musical detail, showcasing superior sound quality.
2. 2DD + 2BA Three-Way Crossover Acoustic Architecture
In this hybrid acoustic structure, the high-frequency units are placed directly in the nozzle. This reduces reflections during transmission and ensures the faithful restoration of high-frequency details, achieving a better synergy with the dynamic drivers. The balanced and natural three-way crossover design maximizes sonic detail. Through extensive research by acoustic engineers, a combination of physical and electronic crossover technologies is used to rationally allocate the low, mid, high, and ultra-high frequency bands across the multiple drivers.
3. High-purity Copper-Silver Alloy Silver-plated Cable
The cable features an 8-core high-purity copper-silver alloy upgrade wire. This ensures a purer sound quality with better high-fidelity detail presentation.
4. CNC Composite Carbon Fiber Shell Craftsmanship
The DH4 utilizes CNC machining for its earphone shells. The unique patterns ensure that every single pair is one-of-a-kind. Every LUMINIS unit is handcrafted by artisans following high-specification standardized processes. From shell fabrication, soldering, and wiring to assembly, polishing, and glazing, every step undergoes strict quality control and inspection. This ensures that a handcrafted product possesses exceptionally refined craftsmanship, with every detail interpreting exquisite artistry.
5. Balanced Airflow Control Technology
Through upgrades to the internal structure and damping, the air pressure between the front and rear chambers of the driver is balanced to an optimal level. This reduces the pressure on the eardrum during listening, making the experience significantly more comfortable for long sessions.
6. Ergonomic 3D Structural Technology
Featuring a "custom-universal" mold design based on a vast database of ear impressions, the DH4 fits the contours of the pinna more closely. This allows you to enjoy a "zero-distance" contact between your ears and the music, ensuring you stay focused on the sound in any environment.
