A communications assembly comprising thin acoustic tubing and an ear insert or an earpiece/extension is disclosed. The ear insert can comprise a reusable foam ear insert. The earpiece can be configured to be captured within a wearer's conchae. The extension can be attached to the earpiece and can be configured to be inserted into the wearer's ear canal. The thin acoustic tube can be configured to communicate sound to the ear insert or earpiece/extension. The use of thin acoustic tubing in combination with an unobtrusive ear insert or earpiece/extension provides an inconspicuous communications assembly that is suited for use in covert operations.
