Search “loose” motorcycle helmet

Hello, I have received a short feedback from you. I am looking for an acoustically very quiet motorcycle helmet. The following problem: 2 years ago I fanned riding a motorcycle. (Before I had a 125er) After my helmet had been on the hump for several years, I bought a new one. At Louis my choice fell on a Shark (doesn’t know exactly which model) Then the first exit: An agony. That was so loud that I thought it was going to tear me apart. The eardrum. Even with earplugs, I felt the sound setting extremely disturbing. I then got a little bit informed on the internet and my choice fell on a slightly quieter Shoei Quest Airfoil. I had set myself as a budget so 300€. (A mistake as I had to notice afterwards) The Shoei was a little quieter than the Shark, but with earplugs it was then half a day. Only at the same time, the fiddle with the earplugs annoyed me animally. Then the one does not sit right, or slips out again, if you stay stuck on the ear when you pull up. Long speech short sense, now I have to make nails with heads and find myself a helmet that I can find from the sound scenery. I leave the price frame outside. Now I have heard from some people that the Shuberth helmets are very good from the accustics. Now I have read the reviews of the SR1 on the Louis homepage. There are beside some good ratings Now the question, who can possibly call me a very quiet helmet from experience, or who has experience with Shuberth helmets, especially with the SR1? My driving profile is actually mainly a country road which I drive but quite a bit more “quiet”. I have a Kawasaki ER-6. I have already thought, however, that it might be on my machine, and I might be in a bad wind, because sc heinbar is the problem with “loud” helmets not so widespread. Thanks already in advance for helpful answers.
