For sunglasses try something close-fitting with straight arms like the Serengeti Vedi ($85 at Peepers). For eyeglasses spend some money on a decent titanium frame (with those springy hingeless arms). For a headset, get one that doesn't depend on any vise-like clamp, or wide sweaty plastic seal to suppress noise. I don't know of any good choices besides the Bose-X. The helicopter community is slowly migrating to Bose ANR (except those goofy North Sea guys with an affinity for Peltors).
