Because each ear is unique

This is our purpose.


After a concert, Quentin, musician and festival-goer, felt a whistle in his ears. He realized that it was the first sign of hearing deterioration.


That's when he decided to protect his ears in noisy environments. He tried different standard protections…but all these protections didn't fit properly in his ears and fall off all the time. In addition, these hearing protections completely isolated him and didn't really protect him!


In 2016, Quentin met Isabelle. He is engineer and she is an audiologist working in this field for several years. The challenge was launched: To develop the best hearing protection by using the latest 3D technologies.


After 3 years of research and development, the two partners launched in 2019 the first store decilo located in Brussels in the Dansaert district. decilo is the first store in Belgium dedicated to hearing protection. Isabelle & Quentin have since developed different custom fit hearing solutions for many applications.
