Abstract
An earplug () with a body front portion () for insertion into a person's ear canal, has a pocket () to increase comfort and is constructed to enhance noise attenuation. The pocket, which allows easier compression of the body front portion for increased comfort, has a plurality of baffles () that attenuate sound better than a pocket without baffles. The pocket with baffles is formed by a core pin () that lies in an injection mold () and that forms the pocket, the core pin having a plurality of slots () that form the baffles. The pocket includes a rear portion () that forms a wide passage, and the earplug includes a blocker portion () that partially or completely closes off the rear pocket passage.
