Customer Review Summary
Introduction to the Grell OAE 2
The Grell OAE 2 headphones, launched in March 2026, represent a refined offering in the open-back over-ear category. Priced at £439, the unit caters to audiophiles prioritising clarity, detail, and comfort for extended listening. The build, featuring zinc housing combined with plush velour earpads and a faux leather headrest, promises durability alongside user comfort.
Design and Build Quality
The open-back design utilises angled dynamic drivers with front-facing sound field modulation, aiming to deliver a natural and immersive soundstage. The circumaural fit fully encloses the ears, while the combination of materials improves breathability and reduces fatigue. Weighing 378 grams without the cable, the headphones feel substantial yet not overly heavy.
The overall aesthetic, in black and silver, presents a professional appearance. The set includes a hard protective case for transport and storage, ensuring the durability of the zinc housing and mechanical components.
Cable and Connectivity
Included is a detachable, flat 1.8-metre cable featuring dual-sided routing for improved cable management. Connectivity options cover a 3.5 mm stereo mini-jack, with adapters for 6.3 mm and 4.4 mm balanced outputs, accommodating a range of devices. A 2.5 mm TRRS headphone jack cable is also provided, expanding compatibility with modern sources and portable amplifiers.
While the detachable cable is practical, the 1.8-metre length is restrictive for some listening setups. Users requiring more flexibility may need to invest in an extension cable.
Acoustic Performance
The Grell OAE 2 delivers a wide frequency response spanning 12 Hz to 34,000 Hz at -3dB, covering and exceeding the average audible spectrum to reproduce subtle overtones and harmonics with precision. The 38 Ohm impedance pairs well with most high-fidelity headphone amplifiers and portable devices without demanding excessive power.
With a sensitivity of 100 dB at 1000 Hz, the headphones efficiently convert electrical signals into sound, allowing for robust output levels and dynamic range. The distortion factor stands remarkably low at 0.05% at 1000 Hz within a 100 dB SPL environment, signifying the capability to reproduce sound without unwanted artefacts or coloration.
Listening Experience
In practical use, the OAE 2 provides clear, natural, and highly detailed sound that enhances both complex studio recordings and more straightforward compositions. The front-facing driver orientation and open-back structure contribute to an expansive soundstage, with instruments placed precisely within the stereo field. Bass response is tight and well-controlled, mids are articulate, and highs extend with clarity without harshness.
The velour padding complements long sessions by mitigating pressure and allowing airflow, contributing to a pleasurable auditory experience even during extended use.
Pros and Cons
- Pros: Excellent clarity and soundstage, very low distortion, robust build with premium materials, versatile connectivity options including balanced cables
- Cons: Short cable length limits movement from source, premium pricing
Conclusion
The Grell OAE 2 headphones offer a technically impressive and refined listening experience, especially suitable for users with a focus on sound detail and spatial accuracy. Their open-back, dynamic design produces a broad frequency range with minimal distortion, supported by a thoughtful build quality that balances comfort and durability. The included accessories complement the package well, though the short cable length could prove inconvenient for some situations and requires additional investment for extension.
Overall, these headphones deliver a precise and natural sound profile confined mainly by minor usability constraints. For the price point of £439, the Grell OAE 2 competently stakes its claim amongst high-end open-back headphones intended for critical listening.
