Recently with the HJC helmet the sound in the helmet is totally different from the ones I am used to with the X-Dot 3/4 helmet. In the X-Dot helmet I have the whistling sound which can mainly be eliminated when I put the visor down. The sound on the HJC is a different kind of wind noise. I can reduce it with the chin curtain installed but that would fog up the visor instead. This sound is made worse when on the Vulcan because the windshield directs the wind up to the head.
This got me researching on earplugs and end up with so many questions: Which are better for motorcycles, which are easier to fit in, are they reusable, which type is better. If possible I do not want the foam earplugs where you have to roll them up before inserting into your ears. I always have this fear of putting it too deep in and will need a trip to the ER to get it out.
If you are wondering about the benefits or how wind sound can damage your ear, head over RideWell and Motorcycle Paradise for more information.
