The replacement eartips were much softer. Noise is without a doubt quieter. Add to this the fact that the bag in which the Crocs were delivered had a different size on it than was on the Crocs we have not had any pleasure whatsoever in trying to purchase a pair of Crocs sliders! I bought three cases to try with my new iPad Air 3, and this was the winner. Ordered these shoes to compliment my summer wardrobe, based on reviews I had a hard time deciding what size to get. Got this for my daughter (12 years old) she is LOVES Riverdale! I bought this to use with a bike rack on a Jeep with a 2? hitch. I actually had to take off my headphones to see if something was going on outside, cause it was a very strange sound. I would say that I have proportionate thighs. Size 5 gives her about an inch of space and so I got these in size 6, and they?re still a tiny bit loose.
