Update *** Despite the quality issue of the sandals we received, the seller was phenomenal to deal with. But you need to have fat or wide feet. Some reviewers had issues with the toe straps not being adjustable (so the triangle dug into their feet), but I didnt have that problem. It?s annoying having to stick my phone in my back pocket or on the cart for it to fall through and to the floor. Was nützt es, wenn das Ding einen guten Klang herstellt, aber Kabel hat, die so lang halten wie jene von einem 10? Ohrstöpsel Teil ! This is a good seat. I highly recommend this for your Index. They are flexible and super adjustable which meant they fit really well on his larger head. I bought the RGB version for myself and the non RGB version for my brother and they are basically identical other than the RGB lighting. But other than that, I love them.
