Selling to declutter. ZOHAN 030 Kids' Noise Cancelling Headphones, Soundproof The safety earmuffs are all wrapped in a cushioned headband, making them comfortable, safe, and stable. The ear pads are made of thick sound-insulating foam and are durable. They do not contain any metal parts that could harm children. Our children's ear protection provides NRR 22dB protection, compliant with ANSI S3.19 test certification (American National Standards Institute) and CE EN 352.1 test certification (European Standard). Note: Children's soundproof headphones reduce noise levels and harmful sounds, rather than completely blocking sound. The adjustable headband and 360-degree rotating noise reduction earphone design are convenient and can be folded compactly, making them convenient for daily carrying. Children's soundproof earphones provide comprehensive noise-canceling headphones for kids for monster truck performances, sporting events, airplanes, concerts, fireworks, and other noisy activities. I opened them for the photos, but they are new and unused. The box is also cute, so it's recommended as a gift! #Soundproofing #KidsHeadphones #NoiseCancelling #ZOHAN
