whatever THIS is. I first purchased a set of COWIN BT on an Amazon Flash Sale, but those were the WORST headphones I have ever heard (and I reviewed those horrid cans! I did win a free one from a scratch off ticket in the package which was shipped fast and I received it yesterday, so I now have a backup if this one fails. I wasnt sure Id find the toe separator comfortable but its fine. My daughter uses them for school and dance practice. Hubby needed slippers for the hospital with no back because he could not bend to put them on. Once you know how/where to grab though it is no big deal just had to train myself to grab them without pushing a button. Muy buenas sandalias, me quedaron muy bien, son muy comodas y bonitas, ademas llegaron en tiempo y forma, gracias. The rubber bands on the middle rack are sized incorrectly and come off constantly. Soft and classy true to size .
