The Noble Audio Onyx sets a new standard in In-Ear Monitor (IEM) engineering, debuting the innovative Quadbrid Driver System. This flagship design integrates eight distinct drivers per channel, expertly combining dynamic, balanced armature, electrostatic (EST), and a Piezoelectric (PZT) Bone Conductor. The Onyx is more than an earphone; it is a meticulously crafted acoustic instrument, engineered to deliver an unparalleled listening experience that pushes the limits of conventional audio fidelity.
Experience a soundstage that is simultaneously vast and intimate, offering holographic imaging and depth that precisely locates every sound source. The eight drivers, managed by a five-way crossover, deliver deep, authoritative bass, pristine mids, and soaring highs, extending up to 70kHz. Crucially, the PZT Bone Conductor adds unique structural detail and enhanced texture, resulting in a deeply immersive and emotionally resonant sound that breathes new life into your music collection.
This sonic excellence is complemented by the Onyx's stunning design. The shells are precision CNC-machined from high-grade aluminium and feature a luxurious Raffir composite faceplate, guaranteeing a flagship look and feel. The package is completed with the high-performance Eletech Courage cable, terminated in 4.4mm balanced, ensuring optimal signal transfer right away. The Noble Onyx is the ultimate choice for listeners who demand uncompromised performance and exquisite build quality.
Driver Configuration
The Onyx uses an 8‑driver hybrid layout that blends a dynamic driver, a bone‑conduction element, multiple balanced‑armature drivers, and electrostatic drivers to cover the full audible range. This multi‑technology approach is designed to deliver authoritative low end, natural midrange presence, and extended, airy highs. The drivers are tuned to work together for coherent phase response and precise imaging.
Sound Signature
The tuning emphasizes clarity and musicality, with controlled bass that supports rhythm and impact without overwhelming the mids. Vocals and instruments sit forward and detailed, while the electrostatic elements add sparkle and microdetail to the upper frequencies. Overall balance aims to suit a wide range of genres from acoustic to electronic.
Build and Finish
Housings are precision machined for rigidity and resonance control, finished with refined faceplate detailing for a premium look. The construction prioritizes durability while keeping weight reasonable for extended listening sessions. Connectors and termination options are robust to support frequent use and cable swaps.
Accessories and Fit
The Onyx ships with a high‑quality detachable cable and a selection of ear tips to help achieve a secure, low‑microphonic seal. The detachable cable design allows for different terminations and easy replacement or upgrades. Tip selection and cable choice are important to optimise comfort and sonic performance.
Use Cases
The Onyx is suitable for critical listening, studio monitoring, and high‑end personal audio setups where resolution and tonal balance matter. Its hybrid driver set makes it versatile across genres and playback systems, from portable players to desktop rigs. The combination of detail retrieval and musical engagement makes it a strong choice for professionals and discerning listeners alike.
Care and Maintenance
Regular cleaning of ear tips and faceplate areas helps maintain hygiene and acoustic performance. Store the monitors in their case when not in use and avoid exposing them to extreme temperatures or moisture. If the detachable cable shows wear, replace it promptly to prevent connector damage.
