I generally wear women’s 9 or 40 with a few exceptions: Dansko 39, Birkenstock 39 narrow, Finn Comfort sandals 39, Ecco 39. I were socks with them for "longer term" use. They are extremely poor. I love in a 13000sq ft apartment and can’t put the max volume on my phone for fear my neighbor will hear; that’s how loud it can get. I was very content with everything I had, honestly. So these are a cheap pair of ballet flats that arent going to last forever, but Ive found that even costly flats tend to wear out quickly. Its a little rough at first but thats not too out of the norm. Compre estos audífonos esperando una buena experiencia en cancelación de ruido, el cual funciona bien escuchando música en alto volumen y sin silencios, pero escuchando música instrumental o clásica es una tortura, se escuchaba una especie de interferencia en al auricular izquierdo al final de pistas o en medio cuando la pista tenía silencios, los devolví y solicite reembolso, volví a pedir otros igual pensando que solo era un error en esa unidad, para mi sorpresa el nuevo set tenía el mismo problema My concern would be the plastic piece that connects to the airpod. the old ones; much more difficult to accidentally knock over.
