I've been using earplugs practically every night for the past three years and I can't recommend them enough. While the particular kind I use (Mack's ultra soft) don't block out all the noise, there is a wide variety of noises that used to wake me up which don't anymore. If you haven't tried them I would highly recommend giving sleeping with earplugs a shot. It only takes a few days or so to get used to them.
In terms of downsides, only once in the past three years did I get some earwax clogged in some part of my ear which was easy to remove with some special spray (went to urgent care). Also, I have a very hard time sleeping without them anymore so I always make sure to have a pair at hand. Also, you may have to experiment with various brands and types as some brands are really uncomfortable and hurt my ear.
Foam are significantly less comfortable for side sleeping and block less noise than Silicone (Mack's) which still come in large sets for well under $1/pair.
I don't know about the 1100 but I have another model (ear classic), just simple foam earplugs, of the same manufacturer. Having gone through many different foam, silicon etc plugs from the pharmacy and grocery shop, the 3M are undeniably the best I've ever had. No pain from the foam expanding bigger than the ear canal (although it's initially bigger), no itching from sweat etc, no pressure on the eardrum when side-sleeping (that tinnitus feeling from some foam earplugs). They are literally perfect, and the noise blocking is the best I've experienced. I don't know what it is but perhaps they have some foam patented that only they use (probably poisonous or something in true evil company fashion though)
The only reason I tried them is that I found myself in a situation where my standard silicone earplugs were gone and where somebody gave me a box of hundreds of earplugs they didn't manage to sell at a concert. I was bracing myself for a terrible night of ear pain, but was pleasantly surprised of how superior they were to anything I had tried, still using earplugs from the very same box as my night-to-night noise relief
I use EAR Classics too. I sleep on a dense pillow, so when there's some noise outside/near the apartment I lay down on the side and put in the earplug into the "top" ear so that the other/bottom ear is then blocked by the pillow. If I change my position during sleep, the noise is usually gone by then (also I tend to be bothered less by noise if I'm already asleep). This is because for some reason I generally sleep better when my ears aren't covered.
That’s all great until something happens while you are sleeping that needs your attention. I’d love to be able to use something like that but being responsible for my family’s safety says I cannot.
Maybe there is room for a device that recognizes those types of sounds and maybe triggers a watch vibration would be a solution.
That's a valid point. Alarms of all sorts do still wake me up, along with crying babies. It worked well when my wife and I were taking shifts being with the baby. When it was my turn to rest, using earplugs definitely made my sleep time more effective.
