I will try an update when I get the next ones. Good sound, seem pretty well-built, the cable is quite substantial in comparison to similar phones. i got a size 5 for my 12 month old -but it would be impossible for you to get a childs foot in here because there is no give in the top. Comes already assembled. Some brands are better than others. The product is just OK! Bought for Bluetooth access to music from my iPhone, but have also found this to be an excellent practice amp for bass guitar (Fender American Deluxe 5-String Jazz bass). so far this laptop has blown it away. - Changing volume should make a clicking noise. you may not have this problem because i had removed and clean my cpu before installing the new memory.
