I have an iPod that I am able to use wired headphones/ earbuds. It had lost its stickiness. Like it just whats on the picture Wrong item shown in picture. Its pretty distracting to see it go on and off, and wondering if it has any negative effects to the device itself. The shoes are much more comfortable with these, kinda like a massage every time you step. I also placed a small bumper pad on the short side of the metal for the same reason. But I still have to give props to their support. a very real product. to avoid toddlers fighting.
