According to the guy in the video they are a lot quieter.
The video review is very interesting. Makes me think about trying a pair. I'm not an aggressive off road rider anyway, I'm probably the 80/20 or even 90/10 rider these are aimed at.
You are on a beach. The sand ripples between your knees. A man tries to sell you a watch; you ignore him. Another man tries to sell you an unpleasant carving.
You call the police.
All is well.
