Thanks for the links! I'll check it all out. I've been using disposable foam plugs but find they drown out too much.And that's why started wearing them all the time. Like I said, it's very mild and not bothersome right now and I feel like it has not progressed in the years since I started wearing them. I find that the noise attenuating plugs, when fit properly don't affect my situational awareness in any meaningful way. Fit is important though, that tight fit feeling in your ear can really mess with you over time as an excessive sensory input. They shouldn't be loose, but if they're too big and fit tight then try another pair.
I got these. I use the longer stalk (grey set) to help with removal and it doesn't interfere with my helmet at all. I use those combined with the included white 25db inserts. It's worth noting that these don't deaden sound as much as foam filters, you still want a good helmet that fits well around your neck. A poor seal at the bottom of the helmet will make a TON of wind noise. They also work really well on loud airplanes, or at concerts. The whole idea is to just bring the sound level down without distorting it, that way you can still enjoy what you're listening to, but at a safe level.
These work really well too, but the stalk was shorter so getting them out of my ear was more difficult.
Remember that for these to work, they actually have to be 'in' the ear canal. It sounds gross, but give them a quick lick and they slide right in, just make sure to wipe them down on a regular basis or it'll taste like earwax. They clean up easily enough and seem to last, I have two sets that are a few years old now. A daily use set that stays in my jacket pocket and a backup in the bike luggage just incase. Oh, and they are made of silicone, so look for a natural rubber pair if you have allergies.
