Titanium Dome + Full Carbon Fiber Multi-Region Diaphragm

At the core of the OSHUN is an advanced composite diaphragm system designed for ultra-fast response and natural tonal balance.

6µm Titanium Alloy Dome

The ultra-thin titanium alloy dome extends high frequencies beyond 20kHz while minimizing breakup distortion.

Benefits

 Crisp and extended treble
 Excellent micro-detail retrieval
 Smooth high-frequency performance
 Reduced listening fatigue
 Enhanced transient response

Full Carbon Fiber Suspension

The 3D woven carbon fiber suspension delivers superior damping and durability compared to conventional diaphragm materials.

Performance Advantages

 Tight and elastic bass response
 Natural low-frequency decay
 Improved diaphragm control
 Long-term fatigue resistance
 Relaxed and organic tonal presentation

This hybrid diaphragm structure creates a highly balanced sound signature with detailed highs and rich, controlled lows.

Dual-Magnet Dual-Cavity Tesla Dynamic Driver

The OSHUN features an advanced 8.3mm Tesla dynamic driver with a powerful dual-magnet, dual-cavity architecture.

Acoustic Benefits

 Nearly double the driving force of traditional single-magnet systems
 Faster diaphragm movement
 Improved transient accuracy
 Enhanced low-frequency control
 Cleaner and more linear sound reproduction

The dual-cavity design eliminates standing waves and improves diaphragm stability for highly accurate sound performance.

Precision Performance

• Excellent square-wave response
• Minimal distortion
• Precise start-stop control
• Smooth dynamic behavior

Simulated Acoustic Cavity for Holographic Soundstage

Inspired by the reflection patterns of real concert halls, the OSHUN utilizes a simulated acoustic cavity modeled from human auricle data.

Soundstage Characteristics

 Wide left-right imaging
 Deep front-back layering
 Realistic spatial positioning
 Expansive holographic presentation
 Immersive live-performance atmosphere

The OSHUN reproduces sound with remarkable depth and realism:

• Vocals appear intimate and centered
• Instruments occupy natural positions
• Ambient details extend far into the background

This creates an incredibly immersive three-dimensional listening experience.

Dual-Core Tuning: Smooth Vocals + Reference FR

The OSHUN is carefully tuned around a neutral reference foundation while adding warmth and musical cohesion.

Tuning Highlights

 Flat and accurate midrange response
 Smooth natural vocals
 Reduced sibilance and harshness
 Balanced tonal presentation
 Excellent emotional expression

The 200Hz–2kHz frequency region remains highly linear for accurate vocal and instrument reproduction, while a gentle upper-mid dip prevents fatigue during long listening sessions.
