I have a Kask Plasma helmet and I am currently using the orange Peltor cans from one of my other helmets. They seem to fit amd seal poorly. I find they also sit on the helmets headband reducing their effectiveness. what cans are you using and what pros and cons have you found? as far as plugs go I use and love them but they are a pain to remove and reinstall when aloft and need to talk to team mates. Thanks for your advice in advance!
