AUNE AR9000 50mm Omni-stack Carbon Diaphragm (OSCD) Open-Back Over-Ear Headphone

As aune’s flagship open-back headphone, the Aune AR9000 brings together a collection of patented technologies, delivering breakthroughs across the diaphragm, suspension, motor system, and acoustic architecture.

Rather than pursuing specifications alone, it is designed to recreate the authentic listening experience of a true reference-grade Hi-End loudspeaker system, with purer signal transmission, effortless dynamics, and an expansive, naturally immersive soundstage.

Carbon Fiber

The Omni-Stack Carbon Diaphragm (OSCD) features a continuous long-fiber structure with no cross- weave and no interruptions. Multiple carbon layers are precisely stacked at optimized angles to create a new generation of high-performance diaphragms. The result is exceptional clarity, resolution, and transient response. Its outstanding stiffness-to-density ratio surpasses that of conventional ceramic, metal, and coated polymer diaphragms, while zone-specific heat treatment further refines damping performance.

Unrestrained Dynamics

Inspired by reference-class loudspeaker engineering, the patented Constant-Flux Linear Motor System delivers an exceptionally long linear excursion of up to 4 mm. This enormous dynamic headroom ensures effortless performance across the entire volume range, allowing the Aune AR9000 to reproduce deep, visceral sub-bass with a tangible sense of air movement you can truly feel.

Stability in Motion

The newly developed suspension system combines ultra-high-damping materials with an asymmetrical variable-thickness structure reinforced by radial stiffeners. This design maximizes stability and control, effectively suppressing unwanted resonances and dynamic compression while maintaining ideal piston-like diaphragm movement.

Precision Acoustic Flow Control

The patented multi-modal acoustic absorption and diffusion system employs precisely engineered open and closed chambers with carefully optimized angles and curvatures. By guiding, diffusing, and absorbing rear sound waves, it delivers smoother midrange and treble reproduction while creating a wider, more natural soundstage.

Designed to Breathe

The Aune AR9000 inherits aune’s signature Tilted Acoustic Matrix architecture while introducing even greater airflow throughout the entire acoustic system. More breathable front and rear mesh structures, combined with highly ventilated earpads, allow air and sound waves to move with remarkable freedom. The result is reduced listening fatigue, enhanced openness, and an exceptionally natural spatial presentation.

Modular Connectivity

An 8-core cable made from high-purity OCC silver-plated copper preserves signal integrity from source to driver. The modular connector system supports 3.5 mm single-ended, 6.3 mm single-ended, 4.4 mm balanced, and XLR balanced terminations, providing maximum flexibility for virtually any audio system.
