Strong magnet, looser fit than I like. Once I hang my headphones on the hanger it weighs it down enough to make the tab in the back not do it's job of keeping the base station from slipping out. I squeezed/pinched/bent the plastic together and it is working for now, but the plastic is flexible and I have a feeling I will be doing this again or needing to put some sort of support on the back. It came with a prybar, so I assumed it would be a tighter fit. Not so much.
