So you can add a little decor. Since I have 2, one for garage and one for house, I think its a general connectivity issue. Dont know if there was a mix up or whatever but I did not receive sliders I received thong flip flops. All in all great purchase. Wanted something that was as comfortable as a sneaker but with a dressier look. I purchased these to go above my stove. Bought a second set with contrasting colors (for identification) for an Accord. 5 stars! They can be used while wearing a hat. While there is a lot of good things about these headphones, there are some problems that can overshadow the areas in where they shine.
