So far I am liking
So far I am liking them very much. Wearing them for long periods they seem to absorb head heat. No sweating issue. And I thought they didn't have good bass sound. Until I found that 2 frequencies that would bring out the bass were turned down. Turned up, and daaaannnnngggg sound so good. With your design even if you had intention or not. They do muffle some background noise.
