Both price are in the same class and range. Both have good sound reproduction and construction. I still cannot make the choice. Plz help and leave some comment. Tell me what do u think about them, which to choose. If you are already a user of one of these two headphones, it will be great to leave some comments to me to take reference to. Thx =]
