The Grell OAE2 headphones represent acoustic engineer Axel Grell’s latest attempt to make headphones sound like loudspeakers rather than headphones. These open-back, circumaural dynamic headphones launch at a premium price point of $599 USD, positioning themselves as a refined evolution of the original OAE1 rather than a revolutionary departure.
Key Takeaways
- Grell OAE2 uses Front-sided Sound Field Modulation (FSFM) technology to mimic loudspeaker listening through acoustic design, not digital processing.
- Open-back design with 40mm bio-cellulose dynamic transducer delivers externalized soundstage and preserved phase/timing cues from head and body interaction.
- Modular construction allows replacement of all parts, supporting long-term durability and user customization.
- At $599, they’re positioned for studio mixing, gaming, and critical listening rather than portable convenience.
- Weight increase of 3 grams over the OAE1 reflects refinements to housing and airflow optimization.
What Makes the Grell OAE2 Different
The Grell OAE2 headphones stand apart through their Front-sided Sound Field Modulation technology, which directs sound from the front of the ear to replicate how loudspeakers interact with room acoustics and human physiology. This approach preserves undistorted frequency response, creates an externalized soundstage, and maintains the timing and phase cues that your head, outer ear, and upper body naturally introduce to sound. Rather than rely on digital equalization or artificial spatial processing, FSFM works through careful acoustic design and material selection.
The 40mm wideband dynamic transducer features a bio-cellulose membrane paired with an innovative damping concept using carefully selected materials for airflow optimization. This combination aims to produce a speaker-like presentation—sound that feels like it’s coming from objects in space rather than drivers pressed against your ears. Axel Grell’s decades of experience at Sennheiser and his own Grell Audio brand inform this approach, though the OAE2 remains an incremental refinement rather than a categorical leap.
Evolution Over Revolution: OAE1 vs. OAE2
The original Grell OAE1 established the open-back, loudspeaker-mimicking formula. The OAE2 improves on nearly identical specifications through an optimized dynamic driver, refined housing for better airflow management, and a wider frequency response. The weight increase of 3 grams reflects these refinements rather than a heavier overall design philosophy. If you own an OAE1, the OAE2 offers precision and tonal accuracy gains, but not a sonic paradigm shift.
This positioning matters. Grell is not claiming to have invented a new category—they’re claiming to have executed the existing category better. The OAE2 premiered at CanJam NYC and is engineered in Germany, reflecting attention to acoustic detail and manufacturing precision. For listeners already committed to the open-back, speaker-like headphone concept, the OAE2 is the refined target. For newcomers, the original OAE1 might deliver 90 percent of the experience at lower cost, though that comparison lies outside Grell’s marketing focus.
Design and Modularity
The Grell OAE2 adopts a modular design philosophy that allows replacement of all parts. This approach extends product lifespan and gives users agency over wear items and potential future upgrades. Balanced and single-ended cables come included, supporting compatibility with studio mixers, portable music players, and desktop amplification systems. The circumaural fit positions them as stationary tools rather than portable commute headphones—they’re designed for spaces where you can sit and listen rather than move through the world.
Intended Use Cases
Grell markets the OAE2 for private music listening, studio mixing, and gaming. The loudspeaker-like soundstage suits music production environments where engineers need to hear spatial relationships and phase interactions accurately. Gaming benefits from the externalized sound field, which can improve directional audio cues and immersion. Casual listening works too, though the $599 price tag and open-back design (which leaks sound and requires a quiet environment) make them a specialist tool rather than a universal daily-driver headphone.
Is the Grell OAE2 worth the price?
At $599, the Grell OAE2 targets professionals and enthusiasts willing to pay for acoustic engineering expertise and modular longevity. If you value speaker-like sound and plan to keep headphones for years, the modular design and tonal consistency justify the investment. If you need portable, noise-isolating headphones for commuting, they are not the right choice.
How do the Grell OAE2 compare to traditional closed-back headphones?
Open-back designs like the OAE2 sacrifice isolation and bass punch for soundstage width and natural timbre. Closed-back headphones trap sound energy, boosting low-end impact and blocking external noise—useful for travel and isolation. The OAE2 prioritizes how sound interacts with your head and body over pure noise control, making them better for stationary, critical listening in quiet spaces.
Can you replace parts on the Grell OAE2?
Yes. The modular design allows replacement of all parts, supporting long-term maintenance and customization. This approach differentiates the OAE2 from headphones designed as sealed units, and it reflects Grell’s philosophy of durability and user control.
The Grell OAE2 headphones deliver on their core promise: a headphone that sounds more like a loudspeaker than a traditional earcup design. They are not a revolution—they are a carefully engineered refinement of an existing formula, backed by acoustic expertise and materials science. For studio professionals and critical listeners committed to the open-back philosophy, they represent a meaningful step forward. For everyone else, they remain a niche tool with a premium price and specific use cases.
