Certified NRR 28, these specially designed noise cancelling ear plugs for kids let youngsters enjoy their active lifestyles with wild abandon. Protect your child's hearing around the home during spontaneous DIY projects or mowing the lawn. A must have for sporting events, fireworks, street parties, parades and concerts, especially younger tots, whose hearing is particularly sensitive. Our Just for Kids Ear Plugs possess all the noise-cancelling properties of our safety ear plugs for adults, but in an extra-small size. The expandable-foam design seals out noise by conforming to little ear canals, all while keeping them in place during boisterous play. Because of the soft, closed-cell skin of our ear plugs, your child can play all day with them in. If they need to be removed, the included cords let your child hang HEAROS around their neck for easy retrieval when playtime resumes. They can be carried in your purse or in your child's book bag for reliable ear protection with the included free carrying case wherever harsh noises would contribute to hearing loss.
