I mean they swivel around, to be clear. How far they are pushed in (if that makes sense) doesn't seem to change, but they swing around on the joint.

I've looked around the internet, a few other people complained about this as well. Have you tried something that makes you your head around a lot, like a boxing game? Something is definitely different about our headsets if you can do that without having the earpieces move at all. Did the design change over time? I don't remember exactly when I got mine, but it was maybe 5 months ago.
