TANGZU Harmonic Empire Xiaoqiao Semi-Open Single Dynamic Driver IEMs

New Concept:-

HE, a brand based on the anime-themed Three Kingdoms-themed aesthetic, created Xiao Qiao, the Mecha Voice Queen. This headset blends the mecha aesthetics of the Three Kingdoms era with a vision of futuristic acoustics. The precision gears of Jiangdong’s craftsmanship mesh with modern military technology, and the agility of Xiao Qiao’s dancing form transforms into the curved aluminum panel. Each note is imbued with the sharpness of the flames of Red Cliff and the delicate beauty of the flowing waters of Wujun. This ultimate listening device boasts full-band control over the audio battlefield and perfectly embodies the concept of musical armor.
Acoustic Architecture:-
5-Axis Aviation Aluminum Alloy CarvingUsing aircraft-grade aluminum alloy and undergoing 5-axis CNC precision machining, the headset boasts exceptional strength, optimized acoustics, a premium panel, and guaranteed quality control.
Resin Precision Casting:-
Precision 3D Resin Printing TechnologyAdopting cutting-edge resin printing technology with nanometer-level precision, we create an ergonomically optimized earphone cavity. This achieves a complex internal acoustic structure, industrial-grade consistency, and agile development.
Design Concept:-
From the flowing iron patterns of Art Nouveau to the modern aerospace-grade Xuanjia algorithmic structure—this open metal panel is more than just form. Inheriting the biomechanical wisdom of the wooden ox and flowing horse from the Three Kingdoms period, within a frame as light as Zhuge Liang’s feather fan lies a ventilation array reminiscent of the Wuzhangyuan repeating crossbow. Furthermore, the mechanical layout of Jiang Wei’s nine expeditions to the Central Plains creates a structural strength comparable to the ships at Red Cliff. Like the skeleton of a mechanical beast that survived the Battle of Yiling, every curve is a fusion of technology and martial arts. The Xiao Qiao is a symphony of precision and nature.We celebrate both the precision of mechanics and the flow of organic matter. These complex curves are more than mere sculptures—they embody the most cutting-edge generative design and acoustic cavity forming technologies, embodying a triple resonance of nature, mechanics, and sound: the strength of bone, the lightness of feathers, the harmony of sound. This is the product of an evolution of design language—when natural inspiration meets computational engineering, precision reaches a pinnacle.The Xiao Qiao utilizes a dynamic driver with a graphene diaphragm, delivering fast, clean, and natural sound. We prioritize purity and coherence over the comprehensiveness of multiple drivers. Graphene’s extreme rigidity delivers lightweight, compact bass, delicate midrange, and crisp highs. All stem from perfect tuning. No phase issues, no compromises, only a unified, authentic sound.
Semi-Open Design:-
The Xiao Qiao’s panel features a semi-open design, breaking through the physical limitations of traditional closed-back headphones, allowing the driver to breathe freely and unleash the sound. potential. It creates a naturally expansive soundstage with realistic imaging and immersive depth. By reducing internal air pressure, it delivers tighter, more controlled bass and clearer midrange. Combined with our advanced diaphragm technology, the semi-open structure creates a sound that is both precise and vibrant.
0.78mm Removable Cable Design:-
The 0.78mm detachable cable, made of premium materials, allows for easy replacement and upgrades. This ensures more reliable and faster signal transmission, allowing for compatibility with a wider range of headphone cables for optimal performance.
Custom Cable:-

We use custom high-end cables from Vortex to deliver superior audio performance and durability, ensuring an enhanced listening experience and reliability through optimized signal transmission.The cable is 1.2 meters long and features 5N Lidz coaxial construction. LC-OFC silver-plated cable delivers crisp, lively sound, adding the finishing touch to the Xiao Qiao. A standard 4.4 balanced plug ensures durability and enhanced practicality.
