I'd love to tell you how good these were


from Best Location in the Nation, OH  -  Quality Oriented

But they were not working correctly when I received them. I've used Koss cans since the Carter Administration & never had an issue. Matter of odds, I guess. On the other hand, the folks at Adorama BENT OVER BACKWARDS to make sure everything was cool. It was my first Adorama purchase... it won't be my last.
