We are the pioneers of mass-produced DLP 3D printing in audio. By developing our own printers and photosensitive resin, we achieve an ultra-high printing precision of 0.25μm.

This allows us to engineer complex internal acoustic chambers that traditional manufacturing simply cannot replicate, ensuring absolute consistency and stability for every unit.

True high-fidelity starts at the source. Unlike brands that rely on off-the-shelf parts, EPZ develops its own core components from LCP+PU composite diaphragms to dual-magnetic circuit dynamic drivers.

Mastering the full R&D stack allows us to perfectly match the driver's physics to the shell's acoustics, delivering a sound that is uniquely yours.

Sound is science.

Our acoustic lab is equipped with top-tier Danish B&K Type 4128C head-and-torso simulators and professional anechoic chambers.

Every frequency curve is rigorously tested and tuned to bridge the gap between objective data and subjective listening pleasure, ensuring minimal distortion and maximum detail.
