Review on Protect Your Child'S Hearing With Noise Cancelling Earmuffs - Perfect For Autistic Kids - 20DB NNR - Toddlers And Kids Age 3-16 Years by Eric Amiradaki

I feel there’s not much noise cancellation I just hear the noise muffled a bit. I got this products for my boys who are diagnosed with ASD and my youngest is more delicate to sound and he got so scared on New Year’s Eve with the fireworks he could still hear them. I think they work best in certain levels of sounds depending on what’s making noise. For example before he would get scared with the sound of drills, lawn mower, leaf blower, and blender and we put him the earmuffs on and it helps him a lot. Could be better but works for certain sounds.
