Purchased this product because of the arch support but unfortunately the fit was not what was expected. Awesome product, Awesome seller! Superbe This only got one start because I have to pick a rating in order to. Comes with super cute "keychains. The bass is how it should be, and its presence can be tweaked using your player eq controls. Do not by from this company. I definitely will to buy these. Its lasted for almost a year and shown no signs of wearing down. 16 worked perfect!
