Onyx: Precise, Powerful, Clear

Introducing Noble Audio's latest flagship IEM, Onyx. Boasting an impressive assembly of eight cutting-edge multi-technology drivers including Sonion electrostats, Knowles BA drivers, custom 10mm dynamic, and a PZT bone conductor, the onyx is a symphony of precision, power, and clarity.

A custom 10mm dynamic driver provides a powerful and controlled bass response, and the ante-chamber design ensures a visceral bass experience.

Mids and highs are flawlessly rendered by four Knowles BA drivers. Dual Sonion electrostatic drivers combined with a PZT bone conductor provide a spacious and immersive soundstage that captures the essence of every note with precision.

Premium Build

The Onyx shell is precision CNC'ed aluminum for durability and rigidity, with a Raffir composite faceplate, and stainless steel wax guard.

The Onyx comes with the Eletech Courage cable. The Eletech Courage cable is a 4 core cryogenically treated flawless OCC Silver-plated Copper cable with 4.4mm termination.
