OK. I present my problem anyway. Now I have Brainwavz M3 and think about the upgrade. M3 is a good headphones, but with a fast, dynamic heavy music to them (or to me?:)) do not have enough mid-bass, aggressive, the sound is soft and cuddly. At the same time as the more quiet music, they sound beautiful. Will GR07 more suited for me, under the given conditions?
