That looks really cool, actually. Is there a way to attach them to the helmet straps?
Gawwwrsh, thanks!! The front of each lens just tucks under the front strap, while the arm tucks into the rear strap. With the right size pair of recycled glasses, and some foam as I said, they stay surprisingly stable. They don't block out much sound at all, just reduce the howl of the wind, which actually unmasks other sounds.
When wearing them, at what speed would you say the wind noise drowns out other noises?
Cool as they are (I find out), I only need em when road riding consistently OVER 15mph or on very windy days. Stick a little port in the foam for a built-in earbud and we have ourselves a patent! Oops, nevermind!
(Thanks all who are still reading this slightly schizo thread...)
