It isn't necessarily the products, though. I've had to keep switching to softer and softer earplugs as my ear canals get sensitized. I wore Hearos Ultimate Softness for several years, now I can't wear them through the night without the pain waking me up. Before that I could wear the orange foam plugs, and before that, pretty much any were okay.
So far I'm doing well with the small Moldex plugs, don't know what they call the model, but if those start getting painful I don't know what's next.
