TANGZU FUDU II — Hybrid In-Ear Monitors

Redefining the Legacy. As the successor to the original FUDU, FUDU II returns with a more refined acoustic design, upgraded craftsmanship, and a vision for the future. Featuring a precision CNC-machined brass shell, natural ebony faceplate, an upgraded 1 dynamic + 2 balanced armature hybrid setup, and advanced crossover tuning, it maintains the Zen-inspired philosophy of balance and restraint while elevating resolution, dynamics, and musical density to new heights.

Key Highlights

• HYBRID2 Architecture: 1 titanium-diaphragm dynamic driver for rich, elastic bass; 2 custom balanced armatures — one for natural, detailed mids, and one for crisp, extended highs.
• Q-AO lite Crossover: Derived from the flagship NEZHA series, ensuring seamless integration, smooth frequency transitions, and phase coherence.
• 5-Axis CNC Solid Brass Shell: High-density metal body enhances resonance control, structural stability, and premium finish.
• Natural Ebony Faceplate: Combines brass with organic materials for a harmonious aesthetic and refined acoustic character.
• Professional Tuning: Balanced, transparent, and natural — delivering a clean background, realistic vocals, and well-controlled low end.
• Ergonomic Fit: Carefully shaped for comfort and stability during long listening sessions.
• 0.78mm Detachable Cable: High-quality 116-core OFC cable for reliable transmission and easy upgrades.

Design & Craftsmanship

Departing from the previous resin + aluminum build, FUDU II uses a precision 5-axis CNC-machined solid brass shell for improved stability and acoustic performance. The front faceplate is crafted from natural ebony wood, offering a balance between “metal and nature” in both visual and sonic character. Brass density ensures controlled resonance, while the ebony adds warmth and elegance to the tone.

Acoustic Architecture

• 1× Titanium-Diaphragm Dynamic Driver (Low): Delivers fast, tight bass with natural decay and excellent control.
• 1× Custom Balanced Armature (Mid): Produces rich, realistic vocals with accurate body and tone.
• 1× Custom Balanced Armature (High): Extends treble smoothly with airy detail and clarity.

Q-IAO lite Crossover

Borrowing the crossover design from the NEZHA series, FUDU II’s Q-IAO lite ensures a unified sonic presentation, low distortion, and consistent phase response. The result is stable imaging, well-layered separation, and an effortless sense of integration.

Tuning Philosophy

Focused on “simplicity with purpose”: bass is full and textured yet never overwhelming, mids are open and natural, and treble is clean, extended, and airy. The result is a balanced, fatigue-free sound signature suitable for a wide range of genres — from ACG and pop to light classical.

Cable & Connectivity

• Cable: 116-core OFC high-purity oxygen-free copper cable for stable signal transmission (upgradeable).
• Connector: 0.78mm 2-Pin detachable design for easy replacement and customization.

Final Thoughts

The FUDU II blends premium materials with a restrained design philosophy to deliver “simplicity with strength.” No excessive drivers, no gimmicks — just well-judged upgrades in every aspect, resulting in tighter bass, more lifelike vocals, smoother highs, and an organic, unified presentation that resonates with the listener.
