Looks like I'm pretty set on the QFR CrossCountry ANR headset. Does
anyone recommend any accessories to go along with it?


I didn't know they offered any. What did you have in mind?



Could someone tell me how much difference there is for the QFRs with
and without ANR in a Cessna?


It's huge.



I'm curious in case I run out of battery
on a Nav flight, would it be disturbing, or as good as any passive DC
headset?

Not quite as good as a regular non ANR but you won't run out. The
little red light will come on with at least 10 hours of battery life left.
