The Elvex Quattro. We used to get them at work. When they decided to move to foamies I ordered two pairs and got hard cases with them. It was about $24.00 for them. I get the corded ones but end up taking the cord out once in a while. I also can pass the cord through the back of a cap or through a sweat band. Hope this helps.
I had a set of the molded ones made a gun show, they worked well. I've heard a lot of complaints about the diy set not hardening correctly. Last I saw they were near $50 for a set made at a show.
