Within the first 2 weeks of running the sole is already falling apart, with the rubber arrow in the back center of the toe completely peeling off both shoes. They still seem to pick up background noise, but Ive had far worse experiences. enjoy the amazing product. I seldom do reviews, but this is an outstanding product! The silicone is picking up cat hairs pretty easily though. paying a premium for the name. Fit perfectly in entry way to keep shoes in order and have a place to sit when removing/putting on shoes or boots its also the cheapest particle board known to man. When on the bass was instantly restored, but the differing materials and ear-to-speaker distance does change the sound signature significantly. Both are very comfortable.
