Abstract
A case for an earbud includes a receiving cavity sized and shaped to accept the earbud within the receiving cavity. The case includes one or more housing magnetic components configured to magnetically attract and secure the earbud within the receiving cavity. The one or more housing magnetic components can be configured to form a Halbach array to increase the magnetic force of the one or more housing magnetic components. The earbud includes a speaker magnet and a separate magnetic element that are arranged to be attracted to the one or more housing magnetic components such that the earbud is attracted into the receiving cavity.
