Hi Everyone Just wanted to share this with you. Our son has Aspergers syndrome which makes him very sensitive to loud and sudden noises e.g. fireworks, shows etc. We were a bit concerned regarding our up coming trip, until we found these childrens ear defenders. They arrived today and are great, DS (4) loves them, especially as he chose the blue ones himself, we are just waiting for bonfire night to check them out, but all looks good so far. The price is very reasonable and I have seen them on ebay. Click here to see the offical website. Hope this is helpful.
