How do you guys get away with using big cup headsets like a Bose X in a 737 or 757? Is it not your airline's SOP to use off-ear cross-cockpit communication or do you use the intercom as standard? How do your colleagues you fly with feel about it? Do they use the same headset as you?
I've used the Bose X in the 747 and it's quite comfortable. I do find that during takeoff or other times of high workload, partially cocking it off one ear helps in cockpit communications. Most whom I fly with, don't use the intercom, and the intercom isn't necessary to communicate.
I've taken to using the Bose QC-15 with the uflymic more now, and it makes hearing others in the cockpit even more difficult. Again, cocking the earphone slightly off the ear still enables me to hear the communication in the earphone, but to hear others talking in the cockpit.
