Audeze CRBN-ELECTRO

CRBN2: The Most Advanced Evolution of the CRBN Series

Originating from an initial partnership related to usage constraints in MRI environments, the first CRBN already marked a breakthrough in the electrostatic headphone world by relying on a carbon nanotube diaphragm. The CRBN2 builds on this foundation and clearly takes it to the next level: 2nd generation transducer, acoustic load optimization, and integration of SLAM technology to reinforce the low end while lowering distortion. The result is a more complete high-end signature, with a wider soundstage, more embodied bass, and an even more evident sense of control on dense passages.

Who Is It For and What Are Its Uses in Hi-Fi and Studio?

The CRBN2 is aimed at demanding audiophiles seeking a listening experience that is both analytical (resolution, separation, spatial precision) and musical (texture, fine dynamics, credible bass). It is also relevant for mixing and mastering engineers who want a highly reliable reading of transients, reverberations, and stereo placement, especially for tracking control and low-level detail verification.
Like all electrostatic headphones, it requires a compatible electrostatic amplifier with 580 VDC "Stax Pro Bias". It is therefore designed for a high-end stationary setup (hi-fi system or studio control room), where conversion finesse, power supply stability, and long-duration fatigue-free listening are prioritized.

Key Technologies and Notable Innovations

SLAM: Deeper, More Tactile Bass Without Losing Electrostatic Speed

The SLAM technology (linear and symmetrical acoustic modulator) acts on the acoustic load to strengthen the foundation in the low frequencies, while helping to reduce distortion and maintain optimal operating conditions for the diaphragm. The result is bass that is more present and physical, with a better-anchored impact sensation, without sacrificing the typical speed and cleanliness of electrostatics.

2nd Generation Carbon Nanotube Diaphragm: Micro-Dynamics and Clarity

The CRBN2 relies on an internally manufactured polyimide film infused with carbon nanotubes to achieve a more evenly distributed electrostatic force. This control improves rendering coherence: sharp attacks, natural decays, readable textures, and excellent tonal stability. The stated frequency response of 10 Hz to 40 kHz illustrates its ability to reach low frequencies while maintaining great openness in the upper spectrum.

Premium Construction: Rigidity, Comfort, and Durability

The chassis combines magnesium, stainless steel, and polymer acetate, complemented by a carbon fiber headband and top-quality leather elements. This approach targets two priorities: limiting mechanical resonances (to preserve precision) and maintaining constant comfort during long sessions. At 480 g, the balance and materials contribute to prolonged listening, a crucial point for mastering, editing, or immersive hi-fi listening.

Pro Bias Compatibility and OCC Cable: Easy Integration into an Electrostatic Chain

The CRBN2 comes with an attached 2.5 m OCC single-crystal copper cable terminated with a 5-pin Pro Bias connector, designed to work with the majority of 580 VDC electrostatic amplifiers. Each unit is hand-assembled and tested in California, with attention to production consistency, a determining factor for this type of precision transducer.
