Powerful Dynamic Driver Unit With Dual-Sided Beryllium Coating:-

DUNU has equipped the EST112 with a large 13.5mm dynamic woofer. It has a dual-sided beryllium coating. Its diaphragm is thicker with a finer & regular grain pattern. It helps bass and lower midrange frequencies maintain their palpable texture and separation with ultra-low distortion ratings.

High-Performance Knowles Balanced Armature Driver:-

High-Performance Sonion EST Drivers:-

Long gone are the days when EST drivers were only being used in high-end headphones. The technology is advancing at a rapid speed with its implementation in many flagship IEMs. DUNU has implemented two high-performance EST drivers from Sonion(a highly renowned audio driver manufacturing brand). They present a smooth, elegant, and well-detailed high and ultra-high frequency response with the EST112.

All-new Lightweight & Elegant Aluminium Alloy Shell:-

DUNU has designed an all-new shell package that encapsulates the re-engineered driver circuitry. The ear cavities are made with a high-precision machining process using lightweight and durable aluminum alloy material. They are finished with scratch-resistant gunmetal anodizing and feature polished stainless steel faceplates for a simple yet timeless design.

Silver-Plated Copper Litz Cable With Patented Quick-Switch Modular Plug System:-

DUNU bundles the EST112 with its premium DUW-02S cable. It is a high-quality Litz braided silver-plated copper cable with DUNU’s patented Quick-Switch modular plug system. Apart from the standard 3.5mm single-ended plug, the package includes 2.5mm and 4.4mm balanced termination plugs.
