Etymotic scares me, have you seen the advise why to not use the Q tip to clean your ears canals ? Because they will push the wax lose and get them deeper into your canals....
I have been wearing my ER-4 since 2004 on nearly every flight and have never had an issue. That probably means that I have had them crammed in my ears for over 2,000 hours. The bonus is that if you use the triple flange tips they automatically remove the earwax out of your ear
