KZ ZS12 Pro 2 – Flagship-Grade Hybrid IEM

Redefining the Limits of Sound

The KZ ZS12 Pro 2 represents a new era of precision and musicality. Designed with a 1DD + 5BA hybrid acoustic architecture, this in-ear monitor delivers a perfectly balanced three-frequency response — deep, powerful bass, clear mids, and refined, distortion-free highs. Whether for professional monitoring, high-fidelity listening, or immersive gaming, the ZS12 Pro 2 offers sound quality comparable to premium IEMs worth thousands.

Golden Acoustic Ratio – Superior Hybrid Design

At its core, the ZS12 Pro 2 combines a 10mm super-linear dynamic driver with five custom balanced armature units to achieve the optimal “golden acoustic ratio.”

Through meticulous tuning and refinement, KZ’s engineers created a configuration that captures the full essence of both dynamic and armature technologies, restoring every musical detail with depth, realism, and precision.

Driver configuration per side:

1. 30019 Mid-High Frequency Balanced Armature (×1)

2. 31736 Ultra-High Frequency Balanced Armature (×2)

3. 31736 Ultra-High Frequency Balanced Armature (×2)

4. 10mm Super-Linear Dynamic Driver (×1)

Unveiling the Layers of Sound

Each earpiece houses two 31736 ultra-high frequency balanced armatures and one 30019 mid-high unit, ensuring seamless frequency separation and detailed reproduction. The result is exceptional clarity and natural tonality — allowing vocals to sound lifelike and instruments to shine with precision.

• 31736 Balanced Armature ×2: Expansive high-frequency extension with brilliant treble openness and resolution.

• 30019 Balanced Armature: Lifelike vocal accuracy for expressive, full-bodied midrange and instrumental detail.

Deep, Dynamic Bass

Equipped with a 10mm ultra-low frequency dynamic driver, the ZS12 Pro 2 produces rich, layered bass with remarkable tension and depth. Its refined diaphragm and optimized magnetic circuit reproduce every note with realism and emotional impact — unlocking a new dimension of low-end performance.

Built-In Electronic Crossover – The “Sound Commander”

An integrated professional crossover board precisely divides frequencies between drivers, minimizing interference and maximizing hybrid performance. Acting as the sound’s “director,” it guarantees consistent accuracy across the full spectrum.

Elegant Design, Built to Last
