This place isn't for you. People here are looking for "flat" headphones so they actually hear how the music is mixed and supposed to sound like. You've probably read all the statements from Dr.Dre.
The artist mixes the music to his/her tastes on what they think is the best, so naturally, the best headphone is one with flat response to recreate the mix perfectly. You're looking for extremely exaggerated bass which THE ARTIST SIMPLY DIDN'T INTEND ON EXISTING. You're distorting the music, mutilating it.
The urbeats = old ibeats. I had them. I loved them at first. Moved up the chain because others are simply better. You can look at my profile for everything I once had.
Once again, the M100 DOES NOT HAVE RECESSED BASS. They are slightly boosted, so you're actually getting more bass than what the artist intends you to hear. I think you have problem with artists not adding enough bass to their songs, and not what headphones you are using.
No offense, you have quite poor judgement of music. It's the lyrics, the melody, the progression, and the dynamics that matter. Not just BOOM BOOM BOOM BASS BASS BASS.
