The new hitch fit over the ball mount without difficulty and we were able to lock it into place. Zudem kommen jedoch auch noch viele verschiedene andere Mikrofone etc. The sole is also very thin and flexible. Washed them and air dried them and smell went away. Not what i expected the size to be. One day of use. They stayed right in place. Over time that may become to much of an irritant for me to tolerate. My son wears these constantly and he loves them. Passt für mich perfekt.
