Our story

decilo was founded in 2019 by Isabelle, a certified audiologist and Quentin, a chemical engineer. As music lovers and having relatives suffering from tinnitus, hearing protection has always been at the heart of our commitment. We decided to reinvent the way how custom fit earplugs are made with the latest 3D technologies. 

Since each ear has a unique shape (like fingerprints), the only way to properly fit your ears is to wear custom made earplugs. At decilo, we offer a wide range of custom fit earplugs to protect your hearing or to improve communication in different situations. We are also making custom fit in-ear monitors for musicians. All our products are custom made in our workshop to be perfectly adapted to the shape of the ears offering an ultimate comfort. We are continuing to innovate in order to offer new and unique products at the cutting edge of technology.
