DUNU EST 112 In Ear Monitor

Welcome to the next generation of DUNU hybrid technology

Quad-Driver Tribrid Configuration - The DUNU EST112 features a quad-driver tribrid setup. It houses a 3rd Generation 13.5 mm dynamic driver with dual-sided Beryllium coating, a Knowles balanced armature and a Sonion dual EST Supertweeter. The unique configuration represents the first foray and next step of DUNU in high-end electrostatic hybrid earphones

Third Generation 13.5mm Large Dynamic Woofer

The EST112 features a large 13.5mm dynamic driver that acts as the woofer in the configuration. It features a dual-sided beryllium coated thick diaphragm that has a fine texture. It provides an impactful, pounding bass response that shooks our soul with every single beat out there.

Ergonomically shaped, with a generous fit kit

DUNU has designed the ear cavities in EST112 with utmost precision to provide a comfortable fit for most users. It is different from their usual rounded ear shells and has an ergonomic shape to them. With proven ergonomics extrapolated from the DK and Studio series, the EST 112 is designed for all-day comfort. A wide array of included ear tips and a soft, lightweight cable allow for the user to listen anywhere.

Proprietary Air Control Impedance System (ACIS)

Leveraging precise control over back-volume air flow, we use a precisionmachined spiral pathway to control the load on the speaker, minimizing rear standing waves and reinforcing sub-bass frequencies

Aluminum Alloy Shell with Stainless Steel Face Panel

The shells of EST112 are made from lightweight aluminium alloy with a high-precision machining process, finished with a scratch-resistant gunmetal anodize and then caped with stainless steel faceplate to improve the looks and elegance of the pair.
