Aune Audio AR9000 Open-Back Headphone

Beyond the Boundaries of Sound

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, Perfected
Every Detail Comes Alive

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
Feel Every Note of the Sub-Bass

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.

Pure Signal - 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.

Built to Last. Designed to Inspire.

The all-metal headband assembly provides outstanding rigidity and long-term durability. Continuing the distinctive design language of the Air Reference Series, the Aune AR9000 combines a sculptural floating architecture with precisely machined details. The deep metallic finish and honeycomb acoustic grille create a refined aesthetic that is both understated and unmistakably powerful.

Science Drives Innovation. Music Remains the Goal.

Countless simulations, prototypes, and refinement cycles have brought together the technologies that define the Aune AR9000. Higher signal fidelity, greater linear dynamics, and precise control over detail, space, and energy allow it to reproduce music with remarkable accuracy while preserving its emotion, impact, and vitality.

The Aune AR9000 is more than a pair of headphones. It is a pursuit of reference-grade sound reproduction without compromise.
