They work, they're comfortable.
I know yhe hype of all the marketing makes them seem like a huge leap in hearing protection.
They're basically just the little earbud plugs you'd get with some cheap headphones from Walmart, with the silicone plug filling where the speaker would normally be. The block way more sound than the advertisements would make you believe.
I found they work as well, no better than several other moto earplugs ive tried, but they were more expensive.
The case is harder...
