Dunu TopSound EST112 In-Ear Headphones
Open-back headphone designs are often higher-performance but have poor noise isolation and leak sound. Closed-back designs provide better noise isolation and leak less sound.
Over-ear headphones sit over your ear and surround your ear with a ring of padding. On-ear headphones are padded but rest on top of your ear. In-ear monitors are worn inside your ear canal.
Speakers and headphones use a device called a 'driver' to create sound. Different types of drivers have different strengths and weaknesses, but can all produce great sound. Common varieties include dynamic, planar magnetic, and electrostatic.
Electrostatic, Dynamic, Balanced Armature
Connectivity refers to the method in which the headphones connect to the audio source. Headphones can be either wired or wireless.

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.
