They have a neat multi-color led light on both sides and they sound good enough for him. Otherwise, value for what I have paid for a month back. Its a little shorter than the picture shows so order one size up :) Gosh, I love these shoes. Totally surpassed my expectations, He is on the heavy side so he tends to go through his house slippers quite often. I’ve only ever worn them indoors. My feet almost reach the top of the slipper, and across the front of my foot it feels a little snug, tight, but if I had ordered these slippers in an extra large they probably would feel better across the front of my foot, but then I could be swimming in them. It came on time. But it held down all my belly flub while doing jumping Jacks and mountain climbers. Beyond that I really only need full throttle and full stop, which I can get with voice command or a quick double tap of W or S.
