摘要

A security and protection device for an ear-mounted audio amplifier or telecommunication instrument. The device includes a resilient water-pervious hollow sleeve sized and shaped to snugly conform to the shape of an audio amplifier or telecommunication instrument having an earpiece insertable in to the ear of a user when the sleeve is slid over the instrument. The sleeve has a top opening at a top end of the sleeve and a bottom opening at an opposite bottom end of the sleeve. The bottom opening is sized to snugly receive the instrument into the hollow sleeve so as to substantially completely cover the instrument when journalled in the sleeve. The top opening is sized to snugly receive through the top opening a corresponding upper end of the instrument. The upper end of the instrument is connected to the instrument earpiece.
