ABSTRACT:
A hearing protection device and method of use intended for a human ear. A plug member caps or enters ear canal, and may be shaped to conform to the external auditory meatus. The plug member may be part of a replacement assembly. The device is biased at least in part by a pressure pad to provide some force against the plug member. An optional handle may be provided to assist with temporarily pulling the plug member away from the ear canal or providing adjustment. An optional bow member clips about the pinna. The device may be adapted for use as an ear phone.
