I also bought the white and blue-grey sandals in this style. The headphones slip easily right in. While I love the look of the shoes, they are not comfortable on my feet. I made sure the indicator light on the earbuds themselves came on to show that they were charging, I?d let them charge until the charging light went off and then try unplugging them and plugging them back in again to make sure they received full charging power, I wiggled the cord as they were plugged in, I left them plugged in for a few days to see if THAT would do it. The shoes are super comfortable however I do not remember in the review or the description it mentioning that they were made out of suede theyre very cute but theyre super hard to keep clean and they get dirty at the drop of a hat I was careful with them and still had to buy a suede cleaning just to bring them back to their color after only having them for a month they came back but its a lot of work They look expensive so that is a great value to me. anyway, i swapped out the nubbies with some other ones i had from another pair of symphonized buds and now i can say they are awesome. Não poderia estar mais satisfeito e contente com o toca-discos. The Bose and Sonys seemed to actually make nearby conversations stand out even worse than when not wearing headphones. I only wear one at a time to be able to hear my toddler, so I can charge one while I wear the other.
