It will grow on you and you will notice how nicely it extends and how much texture it has. It really is nice clean bass amped. It's a signature sound because I have never heard this kind of engaging and charming bass on other headphones. The bass is better on these in both quantity and quality then the D2000's ever would hope to be
It is kind of when I got my D2000's I thought they did not have enough bass but then I realized how well the bass extended. they lacked mid bass slam but the bass was there when needed.
M100's have perfect amount of mid bass slam but not in the mid bass realm of the Pro 900.
