Bone conduction headphones offers the possibility to listen music to deaf people. The bone conduction is a sound propagation method that passes sound not through the air but through bones onto the ears. Hearing people can also listen music, additional the environment noises. We choose to propose a system based on simple components. The aim was to put forward assembly plan accessible to everyone, for a self- manufacture, much less expensive (approximately 50€) and custom-made. All of our work and researches are gathered on a website. We coded a software to optimize the listening of music with the bone conduction. Indeed, bone conduction absorbs some frequency differently than others. Also, we need to be able to rise to volume without overloading the music.
