Grell Audio OAE2 Dynamic Open-Back Headphones

The Next Evolution of the Soundstage. Designed by legendary acoustic engineer Axel Grell (the mastermind behind the iconic HD 600 and HD 800 series), the Grell OAE2 represents a fundamental shift in headphone listening. By reimagining driver placement, the OAE2 eliminates the claustrophobic "in-head" effect of traditional headphones, replacing it with the natural, front-oriented spatial imaging of a high-end stereo speaker setup.

If you are chasing unparalleled depth, mechanical precision, and fatigue-free listening, the OAE2 is your new benchmark.

Key Features

• Front-Oriented Acoustic Geometry: The 40mm dynamic drivers are heavily angled and positioned fully in front of the ears. This allows the sound to interact naturally with your outer ear (pinna) before entering the ear canal, mimicking the experience of listening to nearfield studio monitors placed at a 30-degree angle.

• Bio-Cellulose Transducers: At the core of the OAE2 is a bio-cellulose membrane paired with a custom German-made stainless steel mesh damping system, delivering lightning-fast transients and pristine clarity.

• Fully Modular & Serviceable: Built for longevity, the OAE2 features a sleek, utilitarian design with a full metal frame. Almost every component is user-replaceable, ensuring these headphones can be maintained for a lifetime of listening.

• Scales with Power: Don't let the 38 Ohm impedance fool you, the OAE2 is a hungry headphone that scales magnificently. Feed them with a high-quality amplifier, and watch the dynamics and staging open up exponentially.

The Sound Profile

• Soundstage & Imaging: The defining feature. Music is presented with incredible width and realistic depth in front of you, rather than trapped inside your skull. It is highly cohesive, immersive, and stable.

• Bass: Unusually authoritative for an open-back headphone. The OAE2 digs deep into the sub-bass frequencies (down to 12 Hz) providing tactile rumble and punchy mid-bass without bleeding into the lower mids.

• Midrange: Natural, warm, and rich. Vocals and instruments possess excellent weight and realistic timbre, exactly as you would expect from a headphone tuned by Axel Grell.

• Treble: Smooth, splashy, and relaxed. The OAE2 avoids artificial "air" or harsh treble peaks, ensuring detail retrieval remains completely fatigue-free, even during marathon listening sessions at higher volumes.
