ABSTRACT:
An earplug includes a body, a post and a magnet. The body is made of a pliable material and includes a proximal end and a distal end. The proximal end is shaped to be positioned proximal to the user's middle ear and a distal end is shaped to be exposed to the external environment of the user's outer ear when the body is inserted into the user's ear canal. The post is at least partially embedded within the body and includes a first end, a second end and a socket located at one of the first and the second ends. The magnet is positioned in the socket of the post and is capable of producing a permanent magnetic field.
