I really keep trying to love my HD 25 but i feel them too inconfortable for long periods. I'm a DJ and i listen to music 6/7 hours a day. After that amount of time with the hd 25 my ear hurts and also i feel auditive fatigue.
I bought the Pioneer HDJ X10 and i feel them waaay better in all round aspects, they are more confortable, they sound wider with a lot of soundstage, the feel robust and the cups cover all my ear without touching it, so i can have them for looong periods without pain. I love the bass of the HD 25 but i think that with 50/60 hours of burn in the bass of the pioneers will be even better.
My opinion with the HD 25, i use then for7 month. Really try to get use to them but i couldn't.
