We started decilo in Brussels in 2016. As music lovers and having relatives with permanent tinnitus, we have always been sensitive to our hearing.

We were surprised to not find any modern solution in the market to get earplugs adapted to the unique shape of each ear. This is why we decided to reinvent the way how custom fit earplugs are made with the latest 3D technologies.

As experienced audiologist & chemical engineer, we have spent 3 years of research and development to develop the best custom fit earplugs by using the 3D technology.


In 2019, we have launched our first store decilo located in Brussels in the Dansaert district. We have since developed different custom fit hearing solutions for different applications.
