Look at the dt1350 measurements. Falloff/dip after 100hz where the meat of kicks lie.http://www.innerfidelity.com/images/beyer_dt1350_graph_fr.jpg
They emphasise the sub bass and are wonderful at that, and go nice and now, but for the music I listen to the m100s are a lot better at bass. And a hellofa lot more comfy especially with XL pads.
Of course if you love your mids or want something slightly more neutral the beyers are better there. I'm very interested in the new focal spirit pro as far as closed back neutral professional cans go though: by all accounts they are awesome
