This is why “on ear” headphones exist vs “over ear”.
Depending on your level of comfort, over-ear headphones can be less or more hot than on-ear ones (rests around the ears vs on the ears). Openback headphones are open on the sides so they theoretically should be cooler as well.
Open backed headphones will vent your ears, and they have a richer soundscape
On-ear and small band like ATH-M60x
Try on-ear headphones, like the Koss KPH40s and Koss Porta Pros. A pair of Koss KSC75s on a cheapo lightweight headband has been my professional and home setup for years now and I can wear them for hours and hours on end without fatigue.
You can also go with in-ear monitors. I personally get a mild headache from the audio seal, so I tend not to wear them for too long. Check out Crinacle and Hangout Audio for IEM recommendations.
I’ve mostly transitioned to using in-ear headphones instead of over-ear, partially for this reason.
The other reason being the far less space they take up.
The con is that the battery life is not as good and the sound quality I guess is arguably a bit worse, but on balance I find the tradeoff worth it
