Plugs and four eyes!
I have used Elacin ER-15 earplugs for ten years. Flying in the tropics and in the arctic for up to 8 hours a day (I know - easy life!) I have never had any ear infection problems. The difference in fatigue after a long day's flying when wearing the earplugs is huge.
Being a speccy four eyes can be a problem by breaking the seal on your headset ear cups. I wear titanium framed Silhouette glasses and they are great. They are very thin and flexible. No difference at all in sound and very comfortable.
