This Arai Classic/C helmet is the best helmet I have ever had, and I have had a few since the early 60's. I had WingStuff install the J&M Intergrated headset. What a fine job they did. What a differance in the sound. I was using a H.J.C. with J&M system and it was okay, but not anywhere near as good as this Arai. The old saying you get what you pay for is true. Fine quality products.
