Customer Review Summary
Introduction to the Audeze CRBN2 Design and Build
The Audeze CRBN2 headphones position themselves at the high end of the audiophile spectrum with a price tag of £6,499 and availability since March 2025. Their over-ear, open-back design is built around electrostatic driver technology, promising an extended frequency response from 10 Hz to 40,000 Hz and delivering a maximum sound pressure level above 120 dB. The headphones aim to provide precise sound reproduction supported by a number of advanced materials and engineering solutions.
Construction Materials and Ergonomics
Weighing in at 480 grams, the CRBN2 balances a robust structural composition with wearer comfort. The housing integrates magnesium and carbon fibre, which are known for strength combined with lightness, alongside stainless steel and polymer acetate components. This combination points towards a durable yet refined build quality.
The ear pads are made of premium leather, contributing to a comfortable circumaural fit. This, coupled with an open-back design, facilitates natural sound dispersion but usually requires a controlled listening environment due to ambient noise leakage.
Electrostatic Drivers and Sound Characteristics
A primary highlight of these headphones is the 120 by 90 mm electrostatic drivers utilising Audeze’s patented SLAM driver technology. This technology targets both tactile bass reproduction and high definition spatial imaging, which should provide a holographic sense of soundstage depth and detail.
- Frequency range covers 10 Hz to 40 kHz, extending well beyond the average human hearing range and into ultrasonic territory, which is often associated with the reproduction of subtle harmonics
- Sensitivity of 100 dB allows relatively efficient sound output for electrostatic drivers, which commonly require dedicated amplification
- Distortion factor is specified at less than 0.1% at 90 dB, indicating a very low distortion profile during regular listening volumes
- Maximum sound pressure level exceeding 120 dB implies the headphones can achieve loud playback without compromising audio integrity
Connectivity and Cable Features
The CRBN2 employs a 5-pin Pro Bias connector for its special type cable. Notably, the headphones use a detachable 2.5 metre cable constructed from OCC (Ohno Continuous Cast) monocrystalline copper, a material prized for its purity and conductive clarity. Double-sided cable routing further enhances durability and user convenience.
No adapter is included, so the need for compatible high-voltage electrostatic headphone amplifiers or dedicated bias supplies should be taken into account. This points to an audience of audiophiles or professional users who possess or plan to invest in the appropriate amplification system.
Colour and Aesthetic Details
Finished in a striking Black and Gold scheme, the Audeze CRBN2 exhibits an aesthetic blend of modern luxury and technical seriousness. The colour choice and premium materials align well with the headphones’ high-end positioning.
Conclusion
The Audeze CRBN2 offers a technically advanced electrostatic headphone option, focusing on exceptional sound transparency and build quality. The extensive frequency range, low distortion, and innovative driver technology target those seeking fidelity at the highest level. The weight and comfort features support prolonged listening sessions, although the open-back design necessitates a quiet environment and suitable amplification.
At £6,499, the CRBN2 demands consideration in the context of the user’s amplification setup and listening preferences. The technical specifications suggest a product engineered for detailed, spacious sound reproduction with a focus on bass accuracy and spatial imaging, qualities prized by discerning audio enthusiasts.
