I was thinking about getting this.

I heard if you put it in your headphones it can tighten the bass to make it better.  I have the HD-555, how would I apply this that my headphones could still be an open style?  I have the soundstage mod and re-cabling done to mine so far.

I have Dynamat Xtreme and have modded closed and semi-closed headphones with it before, but not open headphones. I doubt you'd find it worth the expense and trouble with your HD555.
 
It does various things to the sound in headphones that may or may not be found as an improvement.   
 
In car audio it is used to dampen vibrations of the substrate it is affixed to, improve bass response, and increase SPL. 
 
A more direct way to tighten up bass in your HD555 would be to use a more defining DAC/source and/or better amplification.

I've used Dynamat in DIY speakers - it deadens reflections and vibrations. However, the plans called for it to be used.

Headphones are a bit different. Sennheiser spent a lot of time engineering the headphones and if a little damping made an improvement, they probably would have used it. Adding some Dynamat might tighten the bass but it might deaden the highs. There's always a tradeoff. I'm not a headphone engineer and can't second-guess them, so I leave them stock.

While true, with proper judgement and observation it is possible to determine whether the sound engineer or the accountant spent more time on the headphones in question.  My bias leans towards cheap person accountants and market considerations over optimal sound engineering.  You can always make reversible modifications and test for yourself.
