Devices and methods to reduce ear wax clogging of acoustic ports, hearing aid systems, and feedback reduction systems are provided. A conformal hearing aid includes a hearing aid body, where the hearing aid body houses a microphone and a receiver, where the microphone is positioned within the hearing aid body to measure acoustic signals from an ambient environment, and where the receiver is positioned within the hearing aid body to emit acoustic signals toward a tympanic membrane of a user; an expandable element, where the expandable element is operatively connected to the hearing aid body, and where the expandable element is configured to encompass a circumferential portion of the hearing aid body when expanded; and an inflation management system, where the inflation management system is configured to expand the expandable element when actuated.

An earpiece with structure for positioning and retaining the earpiece and with structure for sealing against the entrance to the ear canal to provide passive noise attenuation. The positioning and retaining structure engages features of the lateral surface of the ear. The structure for sealing against the entrance to the ear canal includes a conical structure.

An eartip includes a compliant portion that forms at least a portion of a sound channel, and a wax guard that is supported in the compliant portion and is disposed within the sound channel. The wax guard includes a porous, planar body that permits the passage of acoustic energy but inhibits the passage of cerumen therethrough, and a retention member. The retention member is arranged along an outer edge of the planar body and in direct contact with the compliant portion. The retention member includes a plurality of openings. A compliant material that forms the compliant portion permeates the openings in the retention member to assist in retaining the wax guard in the compliant portion.

Disclosed is a method, a hearing device, and an element configured to be releasably attached to a housing of a hearing device for a user, wherein the element is exchangeable by the user, wherein the element has a dimension which provides that the element is exchangeable by the user's fingers, wherein the element is exchangeable by the user without using a tool, and wherein the element comprises a physical filter configured to be arranged in front of an opening in the housing, when the element is attached to the housing.

The present disclosure relates to dome-type inserts, or simply domes, for a hearing aid. The dome is intended to be attached to a housing, such as an in-the-ear housing, and abut the ear canal. The dome-type insert comprises one or more vent channels for alleviating air pressure built-up and/or occlusion.

The disclosure relates to a battery charger for one or more hearing devices, comprising: a test sound generator configured to produce testing sound; an input configured to obtain first information regarding a first microphone output of a first hearing device in response to the testing sound and obtain second information regarding a second microphone output in response to the testing sound. A processing unit is configured to detect a clogging of a filter such as a wax filter based at least in part on the first information regarding the first microphone output of the first hearing device, and based at least in part on the second information regarding the second microphone output. An output is configured to provide a signal indicating the clogging of the filter.

A magnet in a wireless charger and a ferromagnetic target plate in a hearing assistance device are used to create a magnetic retention force to hold the hearing assistance device in place when charging in order to control an amount of interference with a wireless charging occurring between the wireless charger and the hearing assistance device. A housing for the wireless charger has one or more storage areas. The contours of the storage areas each conform to a shape of the hearing assistance device that will be stored in that storage area.

A wireless charger for a hearing assistance device can include a microphone and a wireless charging circuit. The microphone is configured to receive a wireless communication, including data, in an audio frequency range from a speaker built into a hearing assistance device. The hearing assistance device is configured to amplify sound into a user's ear. The wireless charging circuit of the wireless charger is configured to act as a wireless data transmitter to transmit wireless data in an ultrasonic frequency range, via a charging coil, to the hearing assistance device.
