An earphone capable of making it easy to remove foreign substances that have accumulated on a nozzle portion and easy to control sound characteristics thereof is provided. The earphone includes a driver, a housing defining an electrical component mount on which the driver is mounted, a nozzle portion provided at one end of the housing and defining therein a nozzle hole communicating with the electrical component mount, a nozzle cap detachably coupled to an outer circumferential surface of the nozzle portion, and a nozzle mesh provided at the nozzle cap so as to cover the nozzle hole, wherein the nozzle cap serves to decrease output in a second peak region in a graph of output over frequency for the earphone and to increase a fourth peak region or expand a bandwidth of the fourth peak region in the graph.

An ear bud or cone having multiple protruding, convex and soft elements which are configured to be deformed during insertion, extraction and operation in the ear canal of a person. The soft elements are cushion shaped and thus able to adapt to any shape of the ear canal without exerting excessive force to portions of the ear canal.

Disposable covers configured to at least partially enclose an object that includes a frequently touched surface are disclosed. The disposable cover may include a body having an inner surface that defines an interior space that is configured to receive the object such that the inner surface faces the object, an outer surface opposite the inner surface, and a multi-layer portion that includes an inner layer that is liquid impermeable, an outer layer opposite the inner layer, and an absorbent intermediate layer between the inner layer and the outer layer, the cover further defining an opening that provides access from an exterior of the disposable cover to the interior space.

A hearing restoration system with a housing having a user interface, a pump, control circuitry, and at least one pneumatic port. The hearing restoration system comprises one or more pneumatic ports, which are connected fluidly to one or more tubes. Furthermore, the housing may have a vacuum chamber fluidly connected to the third pneumatic port. A control circuitry is configured to detect a mode of operation of the system based on a measurement of pressure or vacuum inside the hearing aid restoration apparatus.

A dual structure thermoplastic elastomer (TPE) eartip having a wax guard, which is an eartip mounted on one side of an earphone and inserted into an external auditory meatus of a wearer to stably fix the position of the earphone including a core portion formed in a hollow cylindrical structure corresponding to an outer circumferential surface of one end of the earphone and configured with a TPE material having a first hardness value; a wax guard portion formed in a plate-type structure integrally formed with an upper end of the core portion and having a plurality of through-holes formed therein and configured with the same material having the same hardness value as the core portion; and a flange portion formed in a structure continuously forming a curved structure sideward and downward in a radial shape after extending a predetermined height upward from the upper end of the core portion.
