Tangzu Nezha 6BA+1EST Multi-Driver IEM

The Tangzu Nezha represents a significant step forward for the brand, incorporating a custom 7-driver hybrid configuration—six balanced armature (BA) drivers and one electrostatic (EST) unit per side. This setup combines Sonion woofers with Tangzu’s proprietary midrange and treble BAs, while the EST driver enhances high-frequency clarity and detail. The earphones feature a full-resin shell, meticulously designed for ergonomic comfort and effective noise isolation, with an internal 3D-printed acoustic structure to optimise sound delivery.

A key innovation is the Q-IAO electronic crossover, which precisely allocates frequencies across the drivers for a cohesive performance. The striking design includes hand-layered metal flake faceplates, inspired by Nezha’s mythological imagery, while the included OCC silver-plated modular cable offers versatility with interchangeable 3.5mm and 4.4mm terminations.

With an impedance of 16Ω and sensitivity of 106dB, the Nezha delivers an engaging listening experience across a 10Hz–20kHz range. The attention to both technical refinement and aesthetic detail makes it a compelling choice for discerning users.
