The Safe N Sound Ear Defenders are the best! My son has autism and sensory processing issues. He detests loud noises. He can’t even stand it when I vacuum the living room and has to shut himself in his room while I am doing it. These noise canceling headphones keep out the noise perfectly! Obviously, you can still hear some noise, but it is more of a whispering noise instead of a loud bellowing noise. In fact, I threatened to wear them to bed to drown out hubby’s snoring! haha!! They are perfect for kiddos like my Austin, because now he can enjoy the things we enjoy, like the 4th of July fireworks. He even uses them at home to drown out the vacuum cleaner now. These are very much worth the purchase! I received this product for free in exchange for my honest and unbiased opinion and review. Get them here.
