I purchased a new Shoei Qwest based on the ratings for quiet in magazine tests. My wife loves hers, I find it much louder than the Arai Vector we were wearing previously. We always wear ear plugs but my ears get sore after 8 hours with them in and I wanted to be able to ride at slower speeds without them for a while. Bottom line is you need to try a helmet out on your particular bike to find out what really works. Mortons BMW will let you do this (unfortunately I did not ride up there and take them up on that) so check with local dealers to see if one of them will provide that service.
