This QC2 might be good for those of you wearing it, but for the guy sitting next to you it SUCKS.

I hate it when I get a captain that has this headset. The mic picks up sooo much ambient noise compared to a real headset. After a 4 day trip it gets really annoying. Don't forget to take into consideration the people on the other end of the mic. I would much rather my co-pilot no wear these non aviation headsets for this reason.
