A new beginning - a brand new chapter
Redefining the legend of the original with superior sound quality, refined craftsmanship, and a forward-thinking vision. A new chapter begins: tradition meets innovation, performance exceeds expectations, and a new standard is born.

Brass CNC Craftsmanship
Transcending the traditional 3D-printed resin look, Du Fu now features a precision CNC-machined brass body, offering not only a richer and more refined appearance but also enhanced sonic resonance and structural stability. Despite its sturdy construction, Du Fu 2 is meticulously designed for ergonomic comfort, ensuring a secure and comfortable fit for extended wear.

Zen-Inspired Design
Adhering to a new design philosophy, the Tangzu Du Fu 2 replaces the previous aluminum and resin materials with natural ebony, integrating brass and organic elements to achieve a harmonious balance of aesthetics and acoustics. This evolution pays homage to the Zen-inspired simplicity of the original Du Fu while deepening its connection to nature, tradition, and primordial elements—just as Du Fu meticulously composed poems that connect the human spirit with the natural world.

HYBRID 2
Building on the foundation of the HYBRID, the Du Fu 2 features an upgraded driver configuration with a meticulously tuned three-driver architecture—comprising a new titanium diaphragm dynamic driver for richer, more detailed bass, a balanced armature driver designed for natural, detailed midrange, and a third balanced armature driver for crisp, extended highs. This upgrade fully unlocks the potential of every frequency range while adhering to our Zen-inspired design philosophy: returning to the essentials, meticulously enhancing every detail, and eliminating unnecessary complexity.

Q-IAO Crossover Technology
Inheriting the crossover technology of Nezha, the Du Fu 2 has been specially tuned to achieve seamless integration and balanced sound quality between each driver, perfectly complementing its upgraded three-driver architecture. Ingenious attention to detail eliminates redundant design elements.

Inspired by Zen Buddhist aesthetics and equipped with NEZHA series crossover technology, the Du Fu 2 delivers seamless frequency transitions and a smooth, consistent listening experience, effortlessly recreating the essence of music.
