Are they going to give you the best sound experience youve ever had? No, but they arent intended to do so. The material is so flimsy and cheap, sort of like a styrofoam cup. I bought it confidently since it was clearly mentioned in purchase site that it was 2 years warranty. I havent thrown them away yet, but I absolutely will not be buying them again. Bought size 9 for my 8 1/2 feet, fit like a glove, just like my 5 other pairs! Snug fit for a size 14 wide but hubby said they are very comfortable. I love the style and honestly what it seems like is that the straps are just not placed in the right place on the soul of the shoe if they were placed differently they would fit so much better. Currently suffering from a severe bout of plantar fasciitis. Great battery life on a charge too. Ive got narrower feet and found these size 8 have wriggle room.
