UPDATE: Two tips broke off when unplugging them from the binding post and are now lodged in. Inexcusable and an utterly poor product. Solid connection in the binding post with no wobble or wiggle. They require some force to insert into the binding post, but once they're in they remain snug. I also tried removing and reinserting a few times and the connection remained solid. I've used other plugs in the past that have a softer tip and easily deform after one or two insertions. These do not have that issue.
