I teach for an online English teaching company and have gone through multiple headphones before settling on these beauties. They are so comfortable, after 5 hours my ears start to feel a little sore, but that happens with any over the ear headphones, unless you get monster headphones that each cover half your head. My last pair started to hurt after one hour :( I also love the buttons so you can mute them or you. I just got them and am already impressed with the quality. Definitely keeping them, time to take the plastic off.
