"If your primary mode of listening is headphones, I would upgrade them AND get a stand along headphone amp."

I own a set of Senn HD595s because of their versatility: they're easy to drive, and sound pretty good. Driving them off of the Xonar Essence wouldn't be a problem. Given your noisy listening environment though, you might want to consider "closed" cans rather than "open" ones. That may well mean a headphone amp. Maybe look at something like the Beyerdynamic DT770. The iBasso D7 or similar would give you a headphone amp w/built-in 24/192 DAC for about $180. A set of used Beyers for maybe $150, and you'd have yourself a significantly upgraded headphone rig.
