For what it’s worth, I’ve quite enjoyed my aftershokz, on my second pair. The one downside I have is that the wind going over them makes a noise in my ear, and the furry things you clip to your bike helmet straps don’t help enough. don’t get me wrong, you have the wind noise in your ears regardless, but the aftershocks make it worse.
On the plus side, I don’t have to worry about them ever falling off, unlike these, strapped underneath my helmet like they are.
