Monster is the best hidden secret in the headphone industry, thats why I keep buying as many of their products as I can before they go back to being commercially successful again like they were with the Beats times when their prices were outragous like Beats are now. Platform bike racks are the way to go. I got 11s due to reviews here that say these run large (I normally wear 12s) My experience is that they do NOT run large. Initially you see lots of foam as shown in the picture Then you apply it on the car. Do what they say - reduce joint and back pain. The quality of it is great. They comfortably fit over my ears blocking out external noises. Its very light, so you can hardly feel them. Im definitely returning them. Disappointed with these sandals.
