Until we get one in I can only guess what is different. But what we think is that the shell is uniquely shaped to accommodate the ear cups (ear muffs) used in the helmet. The Mag-1 is an inexpensive Sport Mag helmet with ear bud electronics added. The ear buds will not be as clear as the noise-canceling ear cups. We also expect the liner and visor to be of better quality. We will post review once one arrives.
