This was such an easy set-up. Easy to use and has withstood daily abuse so far. First and foremost, I do love these headphones. Also muss eine billige Alternative her. They are a little loose. Firmware 070 may have some issues. I dont usually talk on the phone when Im running. GO. The front rail must be 8 inches from the front of the moon roof, and the back rail should be about 36 inches from the front rail. I removed all bluetooth connections and have no extraneous sources of interference.
