With the Boise, I tend to get a hot spot on top of my head after several
hours of wearing them.

This was an issue with the very early models - I believe that they have a
free upgrage kit available, if you're interested.

Long story...I put a patch of sheepskin (which came as a sample for seat
covers) on my wife's set after she complained about the "hot spot". It
solved the problem. I mentioned it to Bose. They rolled out the upgrade
(with a solution to my battery box complaint too). It impressed me.
