A customized in-ear hearing device includes a light source, photodetector, light emission window, and light transmission window. The light source and the photodetector together function as a physiological sensor by emitting light from the light source through the light emission to the skin of a user's ear canal, and detecting at the photodetector light reflected by the skin that passes through the light detection window. The light emission window and light detection window are located at a customized portion of the sidewall of the device that contacts the skin in the ear canal.

Various embodiments of a hearing assistance device and a method of forming such device are disclosed. The device includes a housing having a shell and a frame disposed at least partially within the shell. An inner surface of the shell and at least a portion of the frame define a void. Further, an indentation hardness value of the frame is greater than an indentation hardness value of the shell. The hearing assistance device also includes hearing assistance components that are disposed at least partially within the void.

A hearing device is provided. The hearing device is suitable for being at least partially inserted into an ear canal is provided. The hearing device comprises a barrier. The barrier is configured to prevent foreign matter inside the ear canal from passing. The barrier comprises a body and a structure. The body has a surface. The structure is a microstructure or a nanostructure. The structure is formed on at least a first part of the surface. The first part is thus configured to hinder the foreign matter from adhering thereto. The structure and the body are monolithic.

A hearing device has a housing in which a receiver is arranged as an electrical component. An antenna arrangement is formed, which has a winding in the form of a coil, which is arranged around the receiver with the interposition of a shielding foil. The shielding foil has a section extending around the receiver and several lugs adjoining it, which project beyond the receiver, the lugs enclosing between them an interspace adjoining the receiver. The shielding foil has in particular two layers, namely a magnetic layer and an electrical shielding layer. By this arrangement an antenna arrangement with high sensitivity is formed and at the same time a shielded partial area is created in the inter-space in which further components can be arranged. Due to the design of the lugs, which are particularly flexible, they can be attached to an inner wall of a housing.
