Saw other more expensive ones but this one is just fine, great quality. We have not slammed them. Once they started to fall apart completely from the sole after a solid 5 years of EVERYDAY wear (seriously, everyday wear) I decided I needed to purchase another pair of black sneakers. Their So soft that while walking your feet slide in them. Its definetly bigger than my Aukey, but not heavy and sounds way better. I thought it was wireless and its not. VERY comfortable, easy to walk in. It is very warm and looks good. I would 100% prefer if the handle was detachable or like the D8 and loose since I keep it in my backpack with my tennis rackets. When using adaptor the maximum range is around 6 feet but using laptop built in bluetooth you can get around 12 feet but some functionality with teams is then lost.
