Our Story

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. 

We have opened our first store decilo located in Brussels in the Dansaert district in 2019. We have since developed different custom fit hearing solutions for different applications. We are now working with already more than 100 audiologist dealers who sell  our products worldwide.

Did you know that each ear is unique?


Like your fingerprints, your ears are unique. Even your left ear is different from your right ear! This is why our products are custom made to perfectly fit your ears.
