The Grell OAE2 isn’t trying to win a spec-sheet arms race. Instead, it asks a more interesting question: what if headphones sounded more like real life?
Developed by Burgdorf-based headphone specialist Axel Grell, the OAE2 is an open-back, over-ear headphone built around a concept Grell calls front-facing sound field modulation (FSFM). In simple terms, the drivers don’t fire straight into your ears. They’re angled so sound reaches the ear from the front—much closer to how we experience music from speakers or live instruments.
With FSFM, the idea is not to overwhelm the ear, but to work with it. By letting sound arrive at a more natural angle, Grell aims to improve spatial perception and tonal balance. According to the company, this results in cleaner mids, smoother highs, and bass that feels present and physical rather than artificially boosted.
Compared to the original OAE1, the OAE2 has been refined in several important ways. The fit has been improved with a revised extension mechanism, a redesigned headband, and new padding. The frequency response has also been subtly reworked to create a more even and coherent soundstage.
Visually, the OAE2 builds on the striking look of the OAE1 Signature, which earned an iF Design Award. The open stainless-steel mesh gives the headphones an industrial, almost architectural feel, while clearly signaling that these are fully open-back.
At 378 grams, they’re not featherweight, but weight is well distributed. The ear pads and headband cushions use breathable velour and memory foam, making long sessions comfortable and fatigue-free.
Modular by Intention
One of the most refreshing aspects of the OAE2 is its modular construction. Ear pads, headband parts, and other components are interchangeable and designed for easy replacement. That’s not just good for repairs—it’s a conscious move toward sustainability.
Grell also emphasizes environmentally certified manufacturing, durable materials, and plastic-free packaging. It’s a modern approach, but without preaching.
Cables and Connectivity
In the box, Grell includes a solid hard case and two silver-plated OFC cables:
-
a 3.5 mm cable with a 6.3 mm adapter
-
a 4.4 mm balanced cable
With a 38-ohm impedance and decent sensitivity, the OAE2 isn’t overly demanding, but it clearly benefits from a quality amplifier or DAC.
A Different Take on High-End Headphones
The Grell OAE2 isn’t about following established headphone conventions. It’s about questioning them.
Rather than forcing sound straight into your ears, it lets music breathe, move, and arrive the way it does in the real world. Combined with thoughtful ergonomics, modular design, and a clear sustainability mindset, the OAE2 feels less like a gadget—and more like a carefully considered instrument.
If you’re curious about new ideas in personal audio and value long-term listening over instant spectacle, this is a headphone worth spending time with.
