SeeAudio KAGUYA II 9-driver, 6-way Flagship In-ear Monitors | Dual BC & EST

Reconstructing the order of sound and pushing the boundaries of listening – the SeeAudio KAGUYA II is the revolutionary next-generation evolution of one of SeeAudio's earliest classic series. Completely redesigned from the ground up, it builds on the flagship MOBIUS crossover tuning framework and adds innovative bone conduction units for unprecedented coherence, density, and immersion.

SeeAudio KAGUYA II – Flagship Nine-Driver Hybrid IEM with 1DD, 4BA, 2BC, 2EST & 6-Way Crossover

This true high-end flagship IEM combines nine drivers per side in a quad-brid configuration (dynamic, balanced armature, bone conduction, and electrostatic) with a sophisticated six-way crossover system. The result? Seamless frequency integration, exceptional phase consistency, natural timbre blending, and a highly cohesive, natural sound across the entire spectrum.

Key Features

• Nine-driver quadbrid hybrid setup per side: 1DD + 4BA + 2 Bone Conduction (BC) + 2 Electrostatic (EST)
• Advanced six-way crossover architecture for precise unit synergy and full-frequency consistency
• Bone conduction drivers add physical density, body, and a sense of realism to the sound
• Ultra-low impedance (13Ω) and high sensitivity (110dB ±1dB) – easy to drive with excellent efficiency
• Wide frequency response: 20Hz–40kHz with tight ±0.5dB QA/QC tolerance for accurate, extended performance
• Low distortion (THD ≤1%) and strong passive noise isolation (26dB)
• Premium OCC silver-plated detachable cable with 0.78mm 2-pin connectors and 4.4mm balanced plug
• Exquisite craftsmanship: Refined ergonomic shell design for superior comfort and consistent sound delivery

KAGUYA II Sound Performance

The KAGUYA II delivers a highly natural, cohesive, and balanced sound profile with great extensions across all bands. Expect:

• Deep, controlled bass with added physicality from bone conduction
• Smooth, detailed mids with excellent timbre and vocal presence
• Airy, sparkling highs from electrostatic drivers without harshness
• Exceptional resolution, imaging, and a wide, holographic soundstage
• Ultimate driver integration – no seams between frequencies, perfect phase alignment, and natural tonal fusion

Whether you're an audiophile seeking flagship-level detail and musicality or chasing the most resolving experience SeeAudio offers, the KAGUYA II sets new standards in multi-driver synergy.
