The Pro-Tec assault is a great all around helmet. The audio interface is super easy to use with cold weather gear on and the headphone output is excellent. You might want to consider a tight skull cap if you ride on super cold days to keep the wind out
My first helmet had issues with the right headphone speaker - probably in the volume control as the volume control continued to work for the left ear.; backcountry.com went above and beyond to ship a new helmet immediately and even gave me the sale price on the new helmet.
