I have the 2012 Smith Vantage helmet with Smith Audio kit which is the same as the SkullCandy ear pads. The cable that comes with the Smith audiokit is horrible, the on/off button and volume knob freezes over. I actually use a monster/beats replacement cable to have audio/volume/iphone controls + mic.... picking up and talking on the phone while shredding the hill is slightly entertaining.
