5cm) as in other reviews. Avoid this and don?t buy it from this seller. I love this product because it really does fast charge my phone. The foam has also lost most of its cushion, especially under the heel. Can?t wait to finish decorating with it. I see that as totally acceptable for the use/abuse I was putting them through and the price point. Super happy with the quality and the flexibility of this unit! The 8s I initially ordered are about the size of the Crocs size 6 he wore last year. If you are willing to pay $100 more you can get headphones that immediately sound noticably clearer, fuller, and louder, but if you were willing to pay that much you probably wouldnt be looking at these. Many people had complained of these being too tight, though theyd ordered a larger size, so Id guessed that a regular size might work well for someone with skinny feet like me, and took a chance on these.
