PRO900, hands down for sure, have more bass than M50 and higher quality to boot.
I think it's easier to "feel" the bass on phones with boomy and loose bass, which doesn't equal to quality.
So probably not to the level you're looking for, but it is enough to satisfy most bass heads looking for quality bass.
TMRaven wasn't too far off when he said Beats if your desire is to "feel" the bass. For hard hitting, tight bass, PRO900 will kick Beats' ass all day long.
Ok well maybe I should be more clear, because the amount that the M50 shake my head is satisfying enough, so I guess I mean how much more can you feel the bass than the M50's bass. Also, when you feel the bass is it always just from air being out the pads or can it also just be the vibration from the drivers.
