摘要:
An earplug having a soft resilient body comprises a main body with a front end for insertion into a human ear canal. The earplug has a stem having two ends, one being attached to the main body and extending outwardly and away therefrom, the other forming a handle. The stem is sufficiently stiff to allow manipulation of the main body into the ear canal and has a crooked or wavy configuration as it extends from the main body to the handle. As the front end of the main body is inserted into the ear canal, the stem is rotated with the handle to fit around the curved portion in the canal. This seats the main body to acoustically block the ear canal while spacing the stem within the curved portion of the ear canal to minimize contact with the sidewalls of the ear canal.
