Professional-grade tuning • Carbon composite dynamic + triple BA • 5-axis CNC one-piece aerospace-grade aluminum body • Ergonomic design • AZLA collaboration
Blending heritage and innovation, TANGZU and AZLA co-developed NOIR BLANC to usher in a new era of in-ear monitors: superior technical performance, precise sound quality, and meticulous craftsmanship—presented as a modern statement of oriental aesthetics.
The one-piece aluminum alloy shell is sculpted via 5-axis CNC machining to achieve micron-level precision and optimal acoustic chamber geometry. The exceptional stiffness-to-weight ratio minimizes resonance and enhances thermal stability—resulting in a cleaner background, more controllable transients, and long-term durability.
Inspired by the lotus and the golden ratio, NOIR BLANC’s panel design mirrors petal-like repetition—purity, balance, and acoustic equilibrium. Every curve and intersection follows subtle geometric law, unifying elegant form and engineering function.
Rich, controlled lows; transparent, natural mids; elegant and well-managed highs. NOIR BLANC aims to reveal micro-detail while retaining warmth and musicality—an immersive soundstage where instruments breathe and vocals carry genuine emotion, presenting the essence of music as a vivid, living art.
