Ours hang from the panel as well and we've not noticed any problems. We
leave ours in the plane, but they do get plugged/unplugged quite regularly
as
Margy has hers and I have mine and we swap them left to right.

We never, ever unplug them. They just each broke, one by one. (Although
it's been a while without a broken cord -- maybe they finally fixed that
flaw?)

Dunno, Margy's is one of the 20K's, she got hers a couple of years before I got mine.
We'd not bothter swapping them except Margy's got some extra gizmo on the headband
of hers.
