Ask any teacher or school staffer about what gets broken first and they’ll tell you that headphones are just too fragile for kids. Not any more, with Marblue’s Headfoam headsets. Made of molded EVA foam, they bend but usually don’t break and are right-sized for kids from pre-K to high school. Available in three colors, HeadFoam headphones have an audio limiter that doesn’t let the sound get any louder than 85 decibels, which can save a child’s delicate hearing. They cost $40.
