Abstract
An ergonomic banded ear plug device includes a band having a connecting section and two legs configured for extending under the chin or behind the back of the head of the wearer. Plug retaining members are at the end of each of the legs for retaining resilient foam-type plug members that substantially block the ear canal of the wearer. In addition, each of the legs includes a resilient flexing section including a pair of parallel extending ribs with a slot formed therebetween. The ribs bendably flex outward and downward to provide a substantially constant force against the ear of the wearer over a broad range of sizes and rotatably flex for improved fit.
