1st off their strong just as expected from the keen brand. (08/06/2019)These shoe trees are amazing out of the box. I amazed that they sell for only $20 ? quite a value. I have found that my topside posts are not well connected. Runs large for a toddler girl and not glittery. (see photos)- Sound quality is not as good as headphones, but definitely good enough to enjoy my music. Nice overall set up and comfortable to use. Adrionak boots perform better in those conditions. You can hear your music at max volume outside of the headphones. It just would not do it not matter what I tried.
