Abstract
Headsets with non-occluding earbuds are disclosed. The earbud includes a non-occluding housing having a directional sound port offset with respect to a center axis of the earbud. The housing can have an asymmetric shape amenable to in-the-ear retention. Additionally, the housing can have a seamless or nearly seamless construction even though two or more parts are joined together to form the housing. Front and back volumes can exist for a driver of the earbud, and embodiments of this invention use mid-mold and rear-mold structures to achieve desired performance from the earbud. For example, the mid-mold structure can be used to tune the front volume while the rear-mold structure can be used to tune the back volume. Apertures may also be included in the housing to further improve the performance of the earbud.
