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:-
