The sound quality is pretty good too. The controls are intuitive and simple. If I’m watching a video, the words match the screen. Never have I ever had such a great cleaner. They are comfortable, keep my feet warm, and works with and without socks. These shoes were just what I needed! PLEASE, READ CAREFULLY:1. Use this primarily for hip thrusts and it works great! Not practical to take two racks from the bed and store in truck while riding or when truck is in the driveway. All in all, this product is really good quality and is definitely worth the buy.
