The sound quality on these is truly outstanding. Easy to install, took like 15 minutes. And now it?s starting to not work, after using it for maybe 4 days. I would say the low end is somewhat missing. Ive been wearing them non-stop for 3 months and the soles are already falling apart. Perfect for him and his feet. I was trying slide it in the slot and it would only go half way. I hung this rack vertically from the high coat rack letting it hang down to where my boys can hang their hats and jackets from it with ease. Wish it got a bit louder but still loud enough for my liking. They also dont have the annoying touch sensitive "technology".
