In these high fidelity wireless inear headphones with noise canceling, the shape becomes an aesthetic and physical guide for the blind use of the product. Physicality thus becomes a function, but it does not forget its artistic being, expressed in a case with elegant and primordial lines. The user interface is minimal: a single LED, hidden under the surface of the product, becomes a single interface for the user, thus allowing the form itself to become a new means of communication, no longer visual but tactile.
