Noisy when visor is open
"As far as the helmet itself is concerned, it is comfortable and lightweight, and I have no complaints in that regard. However, when the visor is open, there is such a loud buzzing and whistling noise inside the helmet that it is almost unbearable. I have owned other jet helmets before, but for a premium brand, this is extremely disappointing, especially considering that city riding is typically done with the visor open. I also own the Shark Spartan RS Carbon full-face helmet, and I am extremely satisfied with it—it has none of these issues."
