Superman 30390 Kid Safe Over the Ear Headphone with Volume Limiter by Sakar;

Large, full-range drivers give you a rich sound experience, with crisp highs and warm, clear bass tones. The ear cups are lightweight with thick, comfortable padding to provide noise isolation, while the headband bends easily for a comfortable fit. The Kid-Safe headphone series features a built-in volume limiter, which protects children's hearing by automatically limiting audio volume to approximately 80 percent of the original maximum volume. These headphones are safe to use for children from 3-9 years old.
