I have a lot of trouble with eye masks, ear plugs.
Not necessarily that I can fall asleep with them (I do), but they cause me to wake at some point in the night to remove. Maybe I have to develop the habit.
Pricey, but look in to Bose SleepBuds ][. Life changing for me. My wife got a pair later and hated them for the first 3 nights ("they hurt, can't sleep", etc) then it 'clicked' and she loves hers too. My brother picked up a pair for $100 on craigslist and... he likes his too (but doesn't use them every night apparently).
