What is ZEN?

A special transmission outside the scriptures, not founded upon words and letters.

ZEN began as a design brief on expressing the ineffable.

Enlightened conception. We took a deliberate, inward look at the fundamental shapes that comprise an in-ear.

Mindful craftsmanship. The same man who designed LUNA, Moses Xu, was tapped to derive its form.

Wavelets through water. The inner facet is sculpted, both for comfort and aesthetic completeness.

Breathe. The vent for DUNU’s proprietary Air Control Impedance System (ACIS) spiral bass reflex system is the centerpiece for ’s circular theme.

The original prototype ZEN was based on PVD beryllium driver technology developed in 2018.

Innovations developed for LUNA prompted DUNU to redesign it for a new performance standard.

ZEN reborn, with trickle-down technology from LUNA.

ECLIPSE a collection of exclusive driver technologies from DUNU.

Standalone metal/alloy/polymer dome
Fully independent suspension surround
Advanced coating and electroplating processes
External ring-type magnet with >1.8 Tesla field strength
Composite assembly and next-gen quality control techniques 
DUNU-exclusive patent (China Patent ZL 2020 2 008721.5)

ECLIPSE is a next generation paradigm for dynamic drivers.

A high displacement, composite driver design with a reinforced alloy dome delivers near-ideal pistonic motion.

This billet-machined, custom Neodymium magnet assembly is the standard bearer for driver control.

Fine-tuned, bespoke strategies for voicing include delicate control of reflected back waves and augmentation of bass reflex

ZEN’s nanoporous amorphous carbon diaphragm coating (nanoDLC) contains the highest ratio* of sp3-to-sp2 hybridized carbon currently achievable, and is deposited via a high temperature, filtered, pulsed cathode arc deposition technique compatible only with metal substrates (polymer substrates will melt and deform). The process allows for fewer gaps and surface imperfections, bringing the layer ever closer to pure diamond.

Engineered by the mind, voiced from the heart.
