I can say without question the hd380 was the worst, didn't feel comfortable at all and it sounded like a tin can. The biggest surprise came when I tried the dt770s. From all the reviews I've read I heard they were the most comfortable. Well definitely not for me. The velour actually made my head itch I though it was very uncomfortable.
All in all I ended up going with the 840s because they actually felt the best and the sound to me was phenomenal and even without an amp which was my goal. I thought about the custom one pro that mal recommended but after hearing the dt770 80s the sound just didn't impress me much and I didn't want to take a chance on returning yet another headphone ( previously I tried the athm50, k550, and grado sr80i).
I always thought I would love the feel of the velour pads but it finally took actually finding a place to try them to change my mind.
