Wouldn't purchase for a child.
Purchased these for my 7 year old, who swims almost daily. These looked impressive and were a reasonable price for 3 pairs. However, fit is terrible! All the "extra" material in the the center is already molded to a certain shape and didn't match up well for my daughter's ear. Plus, there's just too much of it. They came with no instructions or tips to assist with insertion, like pulling ear gently up or down to straighten the ear canal. Also had to cut some of the extra material away and moisten plugs get them to slide into ear canal. Definitely don't recommend for use on children.
