To be honest, these ear muffs were not my first choice, because I was not familiar with the brand. I bought them anyway because these were the only noise protection headphones that would arrive before the event. First, they were the perfect size for my 11 month old (and will be able to be adjusted as he grows for quite some time). He was not uncomfortable, and even wore them crawling around the house earlier in the day as I tested if they bothered or hurt him at all (they didn't). Second, they are well made and seem as though they will last. Third, they work. I know they work because my son slept through his first rock concert, a significant amount of Independence Day fireworks, and the parade the next morning. The parade literally had 19 marching bands and men dressed in colonial outfits firing guns. And still, the baby slept. These are great and I'm recommending them to our friends with babies.
