Tangzu Nezha 6BA+1EST Multi-Driver IEM

The Tangzu Nezha features a custom 7-driver hybrid configuration per side, combining six balanced armature (BA) drivers and one electrostatic (EST) unit. Sonion woofers handle low frequencies, while proprietary midrange and treble BAs work alongside the EST for enhanced high-frequency clarity. The full-resin shell is ergonomically designed for comfort and noise isolation, with an internal 3D-printed acoustic structure for optimized sound.

The Q-IAO electronic crossover ensures precise frequency allocation across drivers. Aesthetic details include hand-layered metal flake faceplates inspired by Nezha’s mythological imagery, paired with an OCC silver-plated modular cable (3.5mm/4.4mm interchangeable). With 16Ω impedance and 106dB sensitivity, the Nezha delivers a balanced response across 10Hz–20kHz.

In the $400 in-ear monitor category, the Nezha demonstrates strong technical execution, particularly in driver integration and high-frequency refinement. Its tonal balance and build quality compete closely with established alternatives, making it a viable option for critical listeners.
