Lightspeed QFR headsets in jets?

[five-alive]

Anyone use these in CRJ or ERJ, active or passive? Are they pretty quiet? How about comfort?

I use the 15XLs in the ERJ and I've got to say, they pick up a lot of noise.. I find myself either apologizing for the white noise or isolating myself by turning the hot mike off. I need to call lightspeed and find out is they offer some sort of filter or level control. But they fit nicely in my flight bag and are extremely comfortable so I'll keep using them since even the DCs pick up some noise at altitute. The noise ain't a show stopper for me, just could be better.
Peace out yo.

Yea I use the 25XLs. They are pretty nice, but I was wondering if anyone had tried their passive line of QFR headsets. Supposedly passive is better for wind noise and ANR is better for low freq prop noise.
