Because the straps go through the car, it is going to compress the door seals causing air leakage and leading to lots of noise. Im so happy. The product itself looks nice but the mold they?re using to create this is off where the controllers built in microphone sits. Have stopped me getting blisters on my heels. I am keeping these only because they are gorgeous and my other Kenneth Cole sandals are about to bite the dust and Ive been unable to find a comparable fancy dress sandal. I dropped one and the tiny screw popped out; secured it with gorilla glue. Dissapointed as I was looking for this very style of ear buds ??. No need to worry about the gps battery running out of juice on long rides. Not to mention they are SO cute. I have a small head and it fits well but expands to a very large size to fit larger heads.
