Method for providing a user with a hearing protection earplug

A method for providing a user with a hearing protection earplug including a shell to be worn at least in part in an ear canal of said user, comprising

• (1) collecting configuration data about audio needs of said user;
• (2) collecting data of an inner shape of an outer ear and ear canal of said user by measuring an actual inner shape of said user's outer ear and ear canal;
• (3) determining, based on said configuration data and said actual ear shape data, a desired shape of said shell;
• (4) manufacturing said shell based on said determined desired shape by an additive layer-by-layer build-up process;
• (5) producing a hearing protection earplug from said shell;
• (6) fitting said hearing protection earplug to said user for verifying that said hearing protection earplug complies with said configuration data collected in step (1),
• characterized in that
• at least one of steps (1), (2) and (6) is carried out in a mobile location.
