Dunu announces EST112 4-driver earphones with triple hybrid design

The Chinese brand Dunu Top-Sound, also known simply as Dunu, has announced the EST112 multi-driver in-ducts. There are actually four sound sources in these headphones, but there are three types of emitters.

A third-generation dynamic 13.5mm driver with beryllium-coated diaphragm is responsible for the low frequency range. It was complemented by the custom armature Knowles – it fulfills the mid-high frequencies. A pair of Sonion electrostatic drivers are responsible for the high frequency range.

All of this is enclosed in an aluminum alloy body with a scratch-resistant anodized finish. Outside the cases are complemented by stainless steel bezels. The DUW-02S cable is made of braided silver plated copper litsedrate.

It features Dunu’s patented modular quick-change system. The owner of the headphones will receive interchangeable earbuds for three connection options: a standard unbalanced 3.5 mm plug or balanced 2.5 mm and 4.4 mm jack options.
