Jerry,
The fact that you can pull the plug out a bit and have proper audio in
both ears speaks to a problem with either the jack in the K3 or the plug
on your headphones. Certainly that cannot be changed by firmware or the
menus, it is simply a matter of something is failing to make proper contact.
Are you using the rear 3.5mm jack or the Front Panel 1/4 inch jack? Are
you using an adapter? Any of those could be at fault.
It might be just a bit of dirt on the contacts in the jack, or a
non-standard ring width on the plug. If using an adapter, then the
adapter is also suspect. It certainly sounds like a mechanical problem
or a plug/jack mismatch to me.
