FAQ Are these earplugs one-size-fits-all? Will they work for people with smaller or larger ear canals?

These earplugs are one-size, with a bullet shape designed to fit most adults comfortably. They are made from soft hypoallergenic polyurethane foam that conforms to the ear canal for a secure fit. However, since fit can vary by individual, if you experience discomfort or feel the seal is inadequate, this earplug style may not be ideal for you.
