Abstract
A noise blocking band earplug has a band (12) with outer portions (44, 46) that are bent to prevent the ear-engaging pods (20, 22) from touching the ground, whether placed right-side-up or upside-down on the ground. When the middle region (32) of the band rests on a horizontal surface (64), a band inner end part (70) extends at an upward incline (C) with its outer end forming a second bend (80) so the outer end part (72) extends at a downward incline (D), with the second bend preventing the pods from touching the ground when the earplug is laid upside-down. At the second bend (80), the largely vertical height (J) of the band is increased and its outer surface (102) is made convex to provide pads for more readily pressing the pods against the outside of the ear canals.
