cooling headphones
over the ear headphones can become warm. A peltier effect cooler could cool the cups, and I am unconcerned with slight warming at the exterior. | |
I was using headphones and I actually ceased listening
because they got warm and stuffy. So, peltier effect
headphones solves it (probably) with the outside of the
headphones on the warm side of the peltier device.
Headphones even come with a power source.

Got kind of a cool heavy metal or punk vibe. [doctorremulac3, Oct 14 2017]

That's achievable. Peltier modules can pump heat in either direction.
What's needed is a thermostat which allows the desired ear
temperature to be set and drives the Peltier element to heat or cool as
necessary. |

I'm not sure if the average music player could provide the necessary power. You'd want about 10W per ear at least, for cooling. |
|

So you'd turn it off when using your mp3 player, but turn it back on when using a computer. Fancy headphones with extra features like lights and buttons do this already |
|
| |
Maybe something more passive like metallic conductive ear
pads with heatsinks around them? |
|
| |
Can you make soft comfortable metal? Perhaps hundreds of
metal beads incorporated into the plastic that extend into
metal rods that stick out porcupine style to radiate the
body's heat energy? |

Or you could have flexible earpads filled with NaK, which is fluid at body temperature. |
|
| |
A system using Ethyl Chloride in a closed system might work - big heatsinks on the headband. |
|
| |
Or we could just be thankful that our forefathers worried
about starvation, plaque, rampaging Mongols or Vikings and
what was then probably known as "sudden death for no
reason, probably demons syndrome" and we're worried about
our headphones being a little warm. |

[doctorremulac3] The real worry of this generation is whether it's Elf-like or Elephant-like product design makes them look in vogue. |
