I've been wearing BTE (behind the ear) hearing aids since I was a kid. So I have the custom molded ear plugs (with hole for tubing) like you mention. I enjoy that they're a magical always-ready pair of earplugs.

But recently trying to use some actual ear plugs to help sleep at a noisy location... I thought they weren't helping, and then I learned from my wife that I wasn't using them correctly. It seems the trick was getting them further in the ear (I think further in than my ear molds go), and voila, more of a difference; better than turning off my hearing aids. I've also noticed the difference recently, using ear plugs when using power tools in the garage (dremel, jigsaw).

So I'm curious if the fitted ones are all equivalent to properly inserted earplugs or not. It's also possible the hole for tubing is the culprit of my observations.

Just another anecdote that might be interesting: audiologists have been doing molded ear plugs since at least the 90s. I remember the posters of cool colorful "swim plugs" back then.

...re-reading: I see now your mention of using various filters. I'll have to read up on that too.

From using regular ear plugs, my experience is that you really need to get them in there quite far. Also, I find that the disposable ones are really basically single use. After they've compressed and expanded I find they don't seem to work as well on subsequent uses. So, taking them out and putting them back in is something I would try to minimize. Maybe they've improved in the meantime?

The molded plugs to me do feel a lot like a properly inserted ear plug and with the filters in, there should be no gaps. It should be a very snug fit. I've got 10db, 17db and 26db filters. The 17db filters are the sweet spot for me, but it's nice to have options.

Cool, thanks for the extra insights!

With (high power) hearing aids, it's reasonably easy to know if you have a gap in the mold: I'll get a feedback loop (annoying noise, naturally) if one is loose or a poor fit. Interestingly, for the past few molds (a 4-6 year life per pair these days) the left ear definitely has more of a problem with feedback loops when my jaw is opened wide (i.e. eating) - the shape evidently varies more with this movement than the right ear does.

The feedback loop sounds rough!

FWIW, I believe these are the filters that I use: https://www.warnertechcare.com/dec-filter-dm-ocean-attenuati...
