Doug S.wrote a review of Smith Skullcandy Single-Shot Helmet Audio Kit on March 23, 2011
Although these came without installation instructions, install was easy. These work really well with the Smith Vantage helmet and are super easy to operate. Awesome combo. I can change volume with gloves on and easily change songs in a second. I wrapped the cord so that the controller sits nicely on the strap. My iPod is new all over again with these in my helmet. They are so worth it.
