Dunu EST 112 4 Driver Hybrid Earphone DUNU EST112 is the latest quad-driver triple-hybrid pair of in-ear monitors. The number 112 denotes the driver configuration of the pair. It is equipped with a large 13.5mm dynamic woofer, a high-performance Knowles balanced armature driver, and two Sonion EST drivers. These four drivers are fitted inside beautiful & lightweight aluminium alloy ear cavities with designer stainless steel face panels. The pair is tuned to produce a relaxing, gentle sound signature with lively, resolving output. Triple-Hybrid Quad-Driver Configuration DUNU has equipped the EST112 with a quad-driver triple-hybrid driver configuration on both sides. The pair features a powerful dynamic driver unit with dual-sided beryllium coating paired with a premium Knowles BA unit and two high-performance Electrostatic drivers. The EST112 is the first pair from DUNU to feature a triple-hybrid driver configuration. 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 DUNU has featured a high-performance balanced armature driver from Knowles in the EST112. It handles the mid-high frequency response in the pair with a transparent and reference response. The pair produces lively and engaging vocals with high-resolution clarity. 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 aluminium 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.
