Born with sword bones and iron bodies, I have braved the flames of war and endured life and death. Forging thousands of blades with pain, I have never wielded a single weapon.

 

Ergonomic design

One circle, two irons

Professional tuning

Q-IAO intelligent crossover system

High-fidelity sound quality

5-axis CNC precision-formed brass housing

Natural ebony panel

Tang Sancai in-house developed earbud tips

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.

Dufu verse 2

Tangzu Dufu verse 2 or Fudu as we call it internationally, landed in the mailbox this morning. Fudu 2 is warm, intimate, musical with sub rumble and good bass. Soundstage is Medium with good details, depth and positioning. The treble leans towards the brighter side and complements the bass well. Changed cable to a GY gold/black that I had lying around and it opened up the soundstage and so far I have only used Tangzu sancai widebore. Brass body and wooden faceplate make Fudu verse 2 look as good as they sound, a bit like a whiskey on the rocks after a hard work week, cheers to you... 🥃 Ps just try the tip roll to Tangzu sancai Noble and the soundstage got wider and treble smoother, I've probably never had a pair of IEMs where both cable and tips made such a big difference. Xduoo xd05t tubeamp used, Dufu verse 2 need good amp to get up to satisfying bass.

Great unboxing and looks!

Tangzu FUDU VERSE II – Full Review
Type: Hybrid IEM (1 Dynamic Driver + 2 Balanced Armatures)
Key Features:
New titanium diaphragm dynamic driver
Two custom balanced armatures
Professionally balanced tuning
Q-IAO Lite crossover technology
CNC-machined brass metal cavity
Natural oak wood faceplate
Tang Sancai eartips (3 bores, S/M/L)
High-purity oxygen-free copper cable
Sources Used:
I ran these off my Topping DX9, iBasso DX340, but mostly the FiiO/Snowsky Melody in walnut to match the color scheme.
Build & Design
The Tangzu FUDU VERSE II immediately impresses in hand. Its precision CNC brass metal body feels dense and sturdy without ever being overbearing. The natural oak faceplate gives it a premium, artisan aesthetic—not exactly handcrafted, but far from cheap-looking. The wood is smooth, slightly warm to the touch, and visually striking. These IEMs are heavy, but in a satisfying way that practically disappears once they’re in your ears.
Cable:
Cable:
I swapped in a new, nice thick cable. It still looks great, is flexible, and feels solid. The upgrade noticeably improved the soundstage, giving more depth and space to the music, and made the listening experience even more immersive.
Fit:
Tang Sancai eartips are some of my favorite and most-used tips. I’ve got the wide-bore versions on both my Alpha/Omega: Fulgrim’s and Omega’s, and now on these too. The FUDU VERSE II aren’t large IEMs, so the fit is excellent—very comfortable for long listening sessions.
Packaging:
For $99, these deliver the most premium unboxing experience I’ve ever had. It felt more like opening a high-end $1,000+ IEM, and I have to say—I love the looks of the whole package.
Sound Signature & Tuning
Bass:
The titanium dynamic driver delivers a punchy, tight low end. It’s controlled but impactful—no boominess. Sub-bass rumble is present but not overemphasized. Kick drums and basslines hit with authority, making rhythmic tracks fun without overwhelming the mids. This all comes through after a good burn-in (20–30 hours) and is especially satisfying when the volume is a little higher than usual—for me, at least.
Mids:
Thanks to the dual balanced armatures, vocals sit beautifully forward. Female vocals sparkle naturally, while male vocals feel intimate and detailed. Instrumental layering in the midrange (guitars, strings, synth pads) is clear—very good, though not perfect. In today’s world of excellent IEMs, they might not be the absolute best at this price, but they still impress.
Treble:
Treble is crisp yet smooth. It’s present enough to reveal detail—hi-hats, cymbals, string plucks—without being harsh. It complements the mids well, with minimal sibilance. Again, very good but not “best ever” territory; still, it’s enjoyable and natural.
Soundstage & Imaging:
With the new cable, the depth and spatial separation are even better. Instruments and vocals feel more three-dimensional, and the sense of space around each element is more pronounced.
Detail Retrieval:
Detail comes through very well, especially at slightly higher volumes. Subtle background elements, ambient sounds, and textures are audible. The metal housing seems to contribute to the overall clarity.
