And I don’t mean this the wrong way. Your experience is anecdotal. Maybe you ride in a city and slow speeds, maybe you have a windscreen that actually does decent job of creating a bubble over you, maybe you don’t ride for extended periods of time. Too many variables to account for. For the population though, ear pro is recommended for Motorsports. I had a bike once that caused buffeting from the hand guards. It might work for you but generally does not work for many.
