I'm not very experienced when it comes to headphones. I was looking for a headphone for portable use (i.e. in the train or just on the go in general). Genres are mainly RnB/Soul, HipHop/Rap, Pop (modern stuff) but I do listen to Rock, Dance and some acoustic as well, depending on my mood. What's important for me is that it has a decent amount of solid and deep bass without being muddy. I do DJ every once in a while but just for fun. Was looking at the HD25-1 ii or some Ultrasones. Haven't been able to try any Ultrasones but I have tried the HD25 and I was very impressed with it's isolation as well as it's sound. I know it's favored by many people and is used for studio monitoring as well as dj-ing. Any other headphones you guys can recommend?
