The paper test doesn't show the punchiness though. It only measures share bass quantities (and it's not that accurate as distance, the positioning/angle of the cup towards the paper all play a role and this is more like "roughly" setup equally), not every1 are in it for the bass quantity, huge bass quantity doesn't necessarily equal to good punchiness. XB700 for example has 15dB subbass boost but the punchiness/impact is low.
That was the point TWek pointed out that Ultrasones do well, they provide a sense of impact/punch in the bass which is seen in the 30Hz square measurement.
Here's the SONY XB700 bass/paper test as comparison

Don't get me wrong - I absolutely love my Signature DJ's, but this visual test beats any frequency response chart dead in the water for demonstrating the SPL of bass "slam" - the paper vibrations act as a visual to what hits your ears/side of face.
