Abstract: An earpiece in accordance with at least some embodiments of the present technology includes a housing and a speaker within the housing. The earpiece can also include an earbud and a protrusion carried by the housing. The earbud can extend from the housing toward a canal of a user's ear when the earpiece is mounted to the user's ear. The protrusion can be at least partially received within a recess at least partially defined by a cymba concha of the user's ear and by an anterior ridge of an antihelix of the user's ear when the earpiece is mounted to the user's ear. The protrusion can include resilient members and intervening slots. The individual resilient members can be configured to preferentially bend relative to the housing in a direction parallel to an adjacent length of the anterior ridge when the earpiece is mounted to the user's ear.
