its literally a put the screw in the hole and twist. What a letdown. I am super happy with them. I like to how I can lower the mic up and down so I dont have to worry about breaking it, cool little feature is the mic can also bend due to the middle part is rubber. LED lights are so cool too! You will see his attempt to show you the movement of these shorts in the photos. The sole is made of what looks like to be a hard rubber that is sealed, so you could wear them outside if you wanted to step out on the porch without getting them wet. Complaints of distortion on the receiver end of the phone call. Comfort and all is great! I like the *idea* that it is fold-able, but its way too flimsy and Customer Service will not stand by their product to my satisfaction.
