Abstract
A hearing protection device for a human ear. The device has an arm that clips about the pinna. A plug member caps or enters ear canal. The device is biased to provide some force against the plug member so that is stays in position during use. An optional handle may be provided to assist with temporarily pulling the plug member away from the ear canal or providing adjustment. The device may be adapted for use as an ear phone.
