I have an iPod that I am able to use wired headphones/ earbuds. We of the slender feet hate spending our summers sliding out the front of our sandals. I wish they were a touch bigger. I asked my husband if he could hear my music- he said no! They stuck really good at first. The mic us detachable and has a muffler and is flexible, quality is fantastic. surprisingly, when the tech open up the wrap, all the professional bolts and washers are in there, saving at least 15-20bucks. It has a gel or rubber top which keeps it in place. Toes and heel are inside the shoe. Id love this keyboard, but it doesnt work, and I cant even blame the keyboard for it.
