Generally speaking, I was happy with the product but then the right earphone started getting really fuzzy and cant hear clearly out of it. I Absolutely love the yellow box fip flops. Much happier with my actual size. Muy bien excelente producto muy recomendable Or they have needed to be wired into a headphone jack, or the Bluetooth would be finicky. They fit my ears, they block probably 95% of the outside noise and the ease of operation is simple after the initial learning period. I don?t even notice it. I would recommend them, but dont expect a perfect fit initially until you wear them awhile (a week or two). The thicker heel makes it easier to walk in and the nude color is perfect for my dark skin, which is hard to find the right shade of nude. I dont think they fit my car.
