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
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.
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.
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
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.

Coming from the FH3 (Fiio) I can say these sound similar... but enhanced in every way. It sounds like one gets even more resolution and extension across the entire frequency range with the EST112. Not that the FH3 were that resolving up top, but these definitely are. As for the bass... there's more of it and its super quick and impactful. The top end is really crisp and resolving. These IEM's have an almost holographic quality to the sound they produce.
