Occlusion devices, earpiece devices and methods of occluding an ear canal are provided. An occlusion device includes an insertion element, a foldable element and an expandable element. The foldable element is disposed on the insertion element and is configured to receive a medium via the insertion element. The expandable element is disposed over the foldable element. The foldable element is configured to unfold, responsive to the medium, and cause the expandable element to expand to contact the ear canal.

An earpiece including an intra-auricular support, a projection element coupled thereto, and a flexible body disposed thereon and inside an external ear canal of an ear, and a moldable earpiece material moldable about the intra-auricular support to conform to the auricle of an ear and curable to provide a fixed configuration of the earpiece.

An earpiece including an intra-auricular support, a projection element coupled thereto, and a flexible body disposed thereon and inside an external ear canal of an ear, and a moldable earpiece material moldable about the intra-auricular support to conform to the auricle of an ear and curable to provide a fixed configuration of the earpiece.

Systems and methods are provided for sealing an ear canal for retaining a solution in the ear canal. Adhesive earplugs are provided through which the solution can be delivered, and which, following delivery, retain the fluid in the ear canal. The systems and methods may also be useful for delivering an anesthetizing solution to the ear canal of a human patient and for maintaining the solution therein for use with an iontophoresis system for anesthetizing the tympanic membrane.

An audio device for insertion into an ear canal of a user that includes an adjustable ear tip. The ear tip is formed by a sleeve disposed on a body of the audio device with a first end of the sleeve coupled to an output end of the body. In a retracted state, the sleeve lies alongside an exterior surface of the body. Movement of the second end relative to the body moves the second end axially along the body and flexes the sleeve radially outward away from the body. An extent of movement of the second end is selectable to provide a radial dimension of the sleeve and thus the ear tip that provides a suitable fit of the audio device with a user's ear canal.

The present disclosure describes eyewear hearing protection systems and eyewear attachable hearing protectors. In one example, an eyewear hearing protection system can include a lens portion that includes a lens to be positioned in front of an eye of a user. A head support can extend back from the lens portion. An earplug dock can be positioned or positionable on the head support. An earplug can be attractable to and dockable on the earplug dock. In another example, an eyewear attachable hearing protector can include an earplug dock including an attachment portion to attach to a head support of an eyewear, and an earplug that is attractable to and dockable on the earplug dock.
