If they ever do loose charge, he always has the option to use them wired as well. My friends and I wore this shoe for our friends funeral and we received so many compliments. This was way easier to assemble than I expected. 5 year old is too little to tell me he doesn’t like them, but the top of his feet look terrible when I take them off: red marks from the folds of stiff fabric pushing into his feet. Just average sounding speaker for the price. It fits well on my 2018 CR v and installation is easy. I processed a replacement request and will update review once I receive replacement. Easy to install, works great I might be on to something here”. Its pretty inexpensive, so I dont want to take the time to return it, but Ill need to buy another one I can use with my computer for meetings, etc.
