Excellent for those with ASD or other sensory challenges, these noise-reducing audio headphones keep sound out and reduce auditory over-stimulation. These headphones are built tough and resistant with built-in strain relief to ensure the audio cord can't be pulled out of the earmuff cups. They've got an internal acoustic treatment that reduces external noise, and they're designed so they can never go above 85 dB - the maximum recommended level for prolonged exposure. Includes a zip-up, hard carry case. For ages 12 months to adult.
