I have seen rfi issues with the QC2 and the Heil noise cancelling headsets. A couple of turns through a snap on fixed that. Neither are great at random shack noises but both seemed to work very well on fixed sounds like fans. I don't doubt that there are better solutions out there. Bose has one heck of a marketing budget!
The folks at Heil told me that they will have some new headphones/sets at Dayton this year that are supposed to be better then the Bose and more rfi proof then their previous headsets and more comfortable.
