Used for games on both astroturf and artificial grass. for the price point. The controls are quite sensitive but after a couple of mile ,I soon got used of them. I have a brand new Denon receiver and two of these Denon Home 150 speakers. That should be very simple. They fit so well in my ear! Don?t buy this product if you?re looking for a sturdy weight rack. Has a great smell to it and is a very good strong smell and the aesthetics look great before making final judgment. Then hear it slide and fall over.
