Smith Skullcandy Single Shot Audio Kit : Instantly add audio to any of your Smith Helmets with the Skullcandy Single Shot Audio Kit. Smith's liners come with a pocket that perfectly hold these headphones and give you crystal clear audio on the slopes. Now you can listen to your favorite music without worrying about your headphones falling off, earbuds coming out, or worse yet, smashing your headphones in a fall. The added single shot feature to this audio kit allows you to adjust volume right from the control on the chord. There is also an added mic built in to the control. Don't pull out your phone or mp3 player when adjusting volume or getting a call. Keep your gloves on, your hands warm, and use the control to adjust on the fly!
