My DS9 has always been sensitive to loud noises. He has consistently watched fireworks with has his fingers in his ears for the past several years. I have tried to get him to wear headphones in the past and he has refused. However, this year he saw some kids at Disney with them on during the fireworks and started asking for a pair of his own. Any advise on kind or brand works the best and where you can find these at a reasonable cost? Any help would be appreciated!
