1. A listening device system comprising:
- an earbud comprising an ear interface portion having a generally convex shaped lower surface that has a curved profile in a first and a second plane that are orthogonal to each other, and a generally elliptical profile in a third plane that is orthogonal to the first and second planes;
a case for the earbud comprising;
a receiving cavity sized and shaped to accept the earbud, wherein a first portion of the receiving cavity is sized and shaped to receive the lower surface;
a plurality of housing magnetic components positioned adjacent one another and located proximate the first portion of the receiving cavity, wherein each housing magnetic component has a contoured top surface that is positioned to form a portion of a concave surface having one or more discontinuities, wherein the concave surface substantially matches the generally convex shaped lower surface of the earbud and wherein the plurality of housing magnetic components are configured to magnetically secure the earbud into the receiving cavity; and
a lid operable between an open position in which the receiving cavity is exposed and a closed position in which the lid covers the receiving cavity.

11. A wireless listening system comprising:
-
(i) a pair of wireless earbuds, each wireless earbud comprising; a housing that includes an ear interface portion having a generally convex shaped lower surface that has a curved profile in a first and a second plane that are orthogonal to each other, and a generally elliptical profile in a third plane that is orthogonal to the first and second planes; a directional sound port formed within the housing; a speaker assembly disposed within the housing and including a driver unit comprising a first magnet, a diaphragm and a voice coil, and wherein the first magnet is operatively coupled to the voice coil to move the diaphragm in response to electrical signals, the driver unit aligned to emit sound from the directional sound port; and a magnetic retention component, separate from the speaker assembly; and (ii) a storage case for the pair of wireless earbuds, the storage case comprising; a pair of receiving cavities sized and shaped to accept the pair of earbuds, each cavity having a first portion that is sized and shaped to receive the lower surface of each respective earbud; a plurality of housing magnetic components, for each cavity of the pair of cavities, each plurality of housing magnetic components disposed within the case and positioned adjacent one another and located proximate the first portion of each respective receiving cavity, wherein each plurality of housing magnetic components has a contoured top surface that is positioned to form a portion of a concave surface having one or more discontinuities, wherein the concave surface substantially matches the generally convex shaped lower surface of each respective earbud and wherein each plurality of housing magnetic components is configured to magnetically secure each respective earbud into each respective receiving cavity; and a lid operable between an open position in which the pair of receiving cavities are exposed and a closed position in which the lid covers the pair of receiving cavities. - View Dependent Claims (12, 13, 14, 15)
