A capacitor in-line of sufficient rating to handle the voltages to be
encountered and with sufficient capacity to pass the lowest freqs of
interest will turn off your ear heaters. Maybe you want to wire in a
"Summer-Winter" switch to be able to select cool or warm operation as the
seasons change.

Heating in headphones and speakers is usually caused by D.C. coming out of
the amp. I underline usually maybe something I'm not considering though.....

Anyone else use earbuds? I've used a set for years with my Flex 3000. I
now have upgraded to a FLEX 5K and when I stuck my earbuds in for the
first time, they were very warm. I thought I had them leaning against
something warm in the shack, but after sitting on the desk for 10
minutes, they are still warm. My ear canals won't get cold, but
clearly, there's something strange going on here. Any ideas?
