I've been reading the reviews over on Amazon and there are so many headphones. Which headphones have you found are the best for a child to help with the fireworks noise? He's 5, but has a big head, so ones for 8+ would work. (Or ones for adults that adjust small enough. But ones meant for the under 8 crowd would be too small). Some reviews say certain headphones are uncomfortable and others don't block out the noise enough. So, I was wondering what the Disney experts use!
