Like many others, I didn't really notice much when I first put them in, but when I took them out, it felt like I was being hit by a truck made out of noise.
I wear them pretty much constantly, unless I'm wearing in-ears for music. I've worn them accidentally when swimming, and they've survived and stayed in nicely.
They're also really, really comfortable, especially compared to the Calmer 2 (sorry, Calmer 2) - they don't really feel like having anything in your ear. I'm quite sensitive when it comes to sensory things, and I don't mind them at all.
I'm writing this with someone typing about half a meter away from me, and while I still hear the sounds of their keyboard, it isn't grating like it used to be. Furthermore, I actually notice a significant difference on days I forget my calmer - I'm more exhausted, I'm grouchier, I have more issues with sensory things and I end up with a migraine more often, too.
They're also essential for certain rowdy D&D-sessions - I used to come home with my head literally ringing from the noise and these days, it's quiet.
They don't really remove any important sounds - voices still sound almost the same, I can still hear everything - except for the painful parts of sound.
That a bit of silicone and metal could make such a difference seems incredible, but that's how it is. They're absolutely worth every penny and if I ever lose them, I'll be sprinting over to order a new pair immediately.
