I disagree, there's a point (quantity and quality) when both subbass and midbass affects mids. Not all midbass emphasized headphones screw the mids, midbass heavy headphones that has little impact on mids would be for example Q40, M100 and Ultrasone Pro900 (the mids are just recessed to begin with), some headphones can deliver that punch but it's a snappy solid punch, it's just a "thump" you feel.
This tight & punchy bass is also interpretable from 30Hz squarewave measurements on innerfidelity for example:
As you see M100 (with stock pads) has very good quality tight punchy bass, the 30Hz squarewave is very short on the vertical length and it has an initial sharp "top" which indicates the punchiness factor, the higher and sharper that "top" stretches the more punchy it tend to get while the shorter vertical length the "tighter" the bass response is. M100 does very well in these regards. PRO900 for example perhaps offers even a bit more punch in comparison if you're into that but still relatively tight bass response but not as tight as M100: http://www.innerfidelity.com/images/UltrasonePRO900.pdf
