1. A single-step process for injection molding an earplug set comprising two earplugs each having a stem providing a grip at one end and a nose at an opposite end with at least one sound dampening member provided towards the nose end, with a cord extending between the two earplugs to connect them together, the process comprising cooling and solidifying a thermoplastics material in a mold which defines cavities configured for injection molding the two earplugs and the cord, wherein said cavities are in communication with one another thereby to permit single-step integral injection molding of the two earplugs and the cord as a single unit made from a single material, and a cord molding cavity is configured to mold sides of a portion of the cord such that the sides adjoin to form a planar annular cord body which surrounds the two earplugs.
