Yeah, to me, when a company has to REALLY sell their product...I'm skeptical. These guys have a ton of videos and it appears that EVERY SINGLE REVIEW is positive! To me, that's a red flag
because there's ALWAYS someone that has something to critique. Ain't no product that good, especially with motorcycle riders. They bitch about EVERYTHING!!!
IMO...if I can get a $5 pair of earplugs that work great then why in the world would I ever throw out another $195 for plugs that will do the same?!?!
Think of it this way, unless you're using an actual pair of ear MUFFS there's only so many decibels you're going to be able to muffle. I mean, put your fingers in your ears around a loud object (wouldn't suggest to do this while riding!) and how much of the sound is filtered? Your fingers should be able to completely cover your ear canal and your fingers are pretty solid.
Therefore, unless you have something covering the entire ear as well (helmet padding obviously helps) there's only so many decibels you can muffle. And I think those $200 plugs are, probably, very good...but I can get similar for a heck of a lot cheaper!
***I will throw out this link:
Not sure how these are but, they make sense! Seems like a homemade-type of kit that you can maybe make yourself.
In the end there are 2 things I do know - 1) there is no such thing as a "Quiet" helmet, only quiet"er" helmets and, 2) to get a total effect of noise suppression you have to go further than covering just the ear canal.
Also, speak with your doctor and ask him/her what they suggest.
