Hi everybody. I'm after a pair of portable, lightweight headphones that I'm planning to use for listening (mainly) to rock/hard rock/metal music. I want them portables but probably I'm going to use them indoors equally much as outdoors as I only own a pair of Porta Pros and I would love to expand my sonic experience a bit. Apart from the Koss Porta Pros, I've never had any other pair of portables or full sized headphones.. I've always had IEMs instead and, as you could expect, my knowledge in this field is rather limited. I'm sitting between Brainwavz HM3, AKG K450 and B&W P3. The P3s are my favourite by far in terms of looks & easthetics and this is why I would be ready to pay a bit more.for them. Of course, I'm open to any other suggestion within a reasonable price tag. Thanks in advance.
