easy install just plugged in with the headphone and works. Purchased as a gift for a picky detailed person. I was able to take it apart and fix it. Basically since this charges multiple devices the little power adapter has to handle more current than a normal adapter. It does come with a nice cute storage box but I can?t imagine having it handy when I need it. I spend a lot of time on my feet when Im working. way too expensive. Can be used to plug into an xbox one controller! These shoes were used for a diabetic who had ulcers to both feet and had gauze wrapped around them. Recently, my workplace issued a rule that we have to wear ear protection, and we couldn?t listen to music anymore.
