This was the second pair of Spenco Mens Kholo Slide Sandals for my husband. I had to pay someone to buy & put it together. The black ones you can control whilst in your ear but the white ones need to be pressed so hard you either push them a mile into your head or you have to take them out. Can always count on Naturalizer to be consistent in sizing. It works (sort of) but with so many other options, this is just not worth buying. Fit great! I also take several calls throughout the day and the quality is excellent. I have a bench with storage bins but its not really enough. When women order mens shoes they have to order two sizes smaller. Less than 20 hours of use between a couple of tablets and four flights and one side is not working when plugged in.
