Premium Craftsmanship & Comfort

• 100% Handmade: Every NC421 earphone is crafted by skilled artisans, ensuring attention to detail and superior build quality.

• Stabilized Wood Housing: The natural stabilized wood not only offers a luxurious, warm aesthetic but also provides excellent acoustic resonance, enhancing sound clarity.

• Ergonomic Design: Engineered for all-day comfort, the earphones fit snugly in your ears without causing fatigue, making them perfect for long listening sessions or on-the-go use.

7-Driver Hybrid Configuration for Immersive Sound

Equipped with a powerful 7-driver system per side (4 dynamic drivers + 2 planar drivers + 1 bone conduction driver), the NC421 delivers a balanced, detailed soundstage that caters to music lovers:

• Dual 10mm Titanium Diaphragm Dynamic Drivers (Opposing): Deliver punchy, tight low frequencies with exceptional cohesion—each beat feels impactful and "punchy to the core," bringing depth to bass-heavy genres like pop, hip-hop, and EDM.

• Dual 6mm LCP Diaphragm Dynamic Drivers (Opposing): Handle mid-high frequencies with clarity and warmth, ensuring vocals and instruments are reproduced with natural tonality.

• 1 Miniature Composite Planar Driver: Elevates ultra-high frequencies with remarkable detail and resolution. Crisp, non-fatiguing highs reveal subtle nuances in music (such as vocal harmonics or string overtones) that often go unnoticed.

• 1 12mm Piezoelectric Bone Conduction Driver: Compensates midrange frequencies, enhancing vocal presence while maintaining a comfortable distance that preserves the soundstage’s spaciousness—balancing emotion and clarity perfectly.
