An improved wireless communications earplug for use with a magnetic field transmitter. The wireless earplug has a receiver made of a coil of wire on a magnetic bobbin, mounted in close proximity or in contact with a magnetic case of a speaker. The magnetic case of the speaker serves to increase the magnetic flux through the receiver and improves the efficiency of the earplug. The speaker is acoustically coupled to an eartip, and the earplug may be molded into a custom earplug body.

A lens selector for selectively exposing one camera lens and covering other camera lenses of a cell phone or the like is shown and described. The lens selector comprises a base which grips the cell phone and a lens cover movable between two or more positions. The lens cover may slide along the base when moving between positions. An arm resiliently biased into an engaged positions may lock the lens cover into a selected position on the base. The lens selector may substantially cover that side of the cell phone having lenses, and may grip edges of the cell phone. The lens selector may include a socket for centering an associated cell phone with respect to an optical device such as a spotting scope, so that the cell phone may capture images visible through the scope.
