Ear plugs. Not electrical, not erm any other type. Ear plugs! Specifically high definition plugs. While watching Shark Tank one of the pitches was for a set of concerns plugs called Vibes. The pitch was that you could wear them to concerts and they would lower the volume, but not the clarity. Seemed like a winner for the slingshot. Crank up the music and ditch the wind noise, right?
So they work reasonably well. Great on a motorcycle and great on the sling. They make it a little harder to speak due to the increased volume of your own voice. They do muffle the purity of music, but not as bad as actual plugs. You can still hold a conversation on a motorcycle while wearing them.
Has anyone tried any other brands? There are quite a few options. I'm thinking of grabbing a couple different brands to see which one is the best because I absolutely love the concept.
