Abstract: An earplug assembly and method of forming the same is described. The method includes uniaxially stretching a cord formed of copolymer including ethylene segments and vinyl acetate segments to form a cold-drawn cord. The cold drawn cord has an elongation to break of 250% or less. The method then includes fixing the cold drawn cord to an earplug.
