Mmm... depends on what you are looking for. the T90 are closed headphones, so they inherently can be a bit warmer on the ears than open headphones as there is no air flow at all inside the earcups for closed headphones. this can be alleviated with different types of earpad material. The Microfiber earpads should be similar in breathability to velour/vegan earpads. So if you need noise isolation of a closed pair of headphones, I would imagine it doesn't get much better than something like the T90 in terms of ear warmness. May be a bit weird if you are transitioning from speakers to headphones, but it really shouldn't bother most people. If you don't need to noise isolation, you can try any open pair of headphones with velour pads, which should feel less warm. No need to go specifically with the Hifiman brand, there are a wide variety of options out there. If you like your current brand, Beyerdynamic will have open headphones with velour earpads at a variety of different price points. hope this is helpful.
