For reference, I tried a 10, and it felt stifling. They scuff easily but overall I was surprised by the quality for the price: absolutely recommend I can smell them when I am sitting down with them on. They seem to be designed to wear on either foot, given that they are as uncomfortable whichever foot they are on. It is so easy to pop one of these into the washer with no dripping container to contend with. I didnt fully read the description to realize its not a earbud but more like iPhone ones. El producto está bien, se ve resistente y es muy bonito, pero del toallero largo venía dañada la pintura de un extremo, no es muy relevante pero al tratarse de un producto nuevo debería venir sin detalles The appear to be good quality and are comfortable. Since I live in California its no big deal. Adjust your EQ to taste.
