3M™ E-A-R™ Flexible Earplugs HA have a patented protective foam composition, making the earplugs fully washable and reusable. The soft foam tip and flexible insertion handle allow for easy insertion into the ear with one or both hands. The soft foam tip conforms to the unique shape of the ear canal, helping to dampen surrounding noise. The cord keeps the earplugs readily available and helps keep the foam tips clean between uses. Flexible earplugs are particularly suitable for activities that require gloves or where hands get dirty, or for situations where the user has only one hand available to insert the earplugs.
