Introducing the Dekoni x Hifiman Cobalt!  ·  Source: Dekoni


The Dekoni Cobalt is a dynamic closed-back design created in partnership with Hifiman. Making use of the latest driver technology and wooden earcups from Hifiman, the Cobalt has then been specially tested and tuned by Dekoni’s in-house engineer.


The aim is to produce a pair of audiophile-grade headphones that is lightweight and comfortable to wear, but most of all an absolute pleasure to listen to. Let’s find out more about this interesting new design!

A closer look at the Dekoni Cobalt

The way that the Cobalt driver is designed allows the carbon coating to cover any part of the diaphragm. This meant that it provides ample room for fine-tuning, where nano-meters are coated onto the driver in order to adjust the speed of the diaphragm. This became the focal point around which, the entire design was based.

Over the duration of the 5-month testing period, various materials were tested in the earcup behind the driver. Any changes made a big difference, and the trend showed that certain materials decreased the soundstage while allowing an extended low-end response.

Overall, the Cobalt is a worthy alternative to the HD-600 with a unique driver system, and the closed-back design offers a more discrete listening solution. Its unique driver design is a promising selling point and the fact that it comes from a manufacturer that specializes in headphones makes it worth checking out.
