I'm kinda concerned about this. If they fall off my head while I'm groovin this takes a bit of the fun out listenining. So do they? Or are they just super shifty?

ATs are very ear hugging, Grados fall right off, Etys are stuck IN your ears, don't know about other brands.

With the A-T phones the inertia is the cause of concerns about this, I think. They're all not that light (<>350g) so if you're doing a Death Metal In-Concert scenario, then the phones move around due to inertia.
But we are talking serious head-waving here... Undernormal circumstances they stay on fine

And it's not like you don't get fair warning.
