I just use the ones in the airplane as do most guys I've flown with. I've only known a handful that actually bought their own. The ones they provide are nice. Isn't very loud up there. We can take them off and talk no problem. I just put earplugs in under them and within 10 seconds forget I'm even wearing any. They give you sterile wipes to clean everything with.
i don't know how some of you guys use the same headset, why not wear the same underwear?
Who wears underwear?
