Overall Review: I absolutely love these! They were definitely worth the price they are so so cute and fit perfectly snug. Does not cost a fortune. These came with extra rubber pieces to replace so that's definitely a plus! They are super loud. Love that! Battery life is great. It even tell you what percent they are! A really good Christmas gift to friends and family. My best companion in the walks now.
