Okay, I got off a four hour session yesterday with the 3D Pulse headset anf made sure not to take it off when I was AFK for this thread and after a bit more than four hours all there was that was uncomfortable was a slight bit of sweat in my hair where the cups were making contact. It never once touched either of my ears nor gave them any discomfort or moisture or itch and elastic the strap on top that helps that from happening didn't even leave a flat mark on my hair or any sweat.
Years ago I used to use fairly high end headphones for PC and PS4 and this thing while it's range and bass is not as good is pretty much better in every other way for about one third the price and by far the most comfortable headset I've ever used. You can't use it for anything else than the PS5 and the mic gives feedback (if you'll be using it for that, I turn it off) but as a dedicated PS5 headset, it's amazing and it allows for better 3d audio and Dolby atmos than stereo buds. Only a 100 euro. So all on all, unless you have particularly large ears this is top notch and perfect for the comfort issue you made this thread for, I would ask in store for a try on and if the cups don't touch your ears buy it. You won't regret it.
