I wondered about the Calmer product for a long time and decided to pull the trigger for myself and my wife. I've had tinnitus for well over 10 years and my wife has been experiencing ear sensitivity and blockage issues lately. The product itself is very basic and doesn't seem to warrant the price tag of about $25. Once we tried them, however, the difference was noticeable. Bothersome high-pitch frequencies were dulled and painful sensitivity was lessened, maybe not by 100%, but certainly well above 50%. My issue is that I don't want them in all the time, and putting them in is a bit of a chore. They're very small and tend to slip out unless you remain upright at all times. I think I've used them about 3 times in the past 2 weeks, mostly out of laziness. On another note - I didn't realize these ship from Europe, so definitely plan on them taking at least a week to get to you, and probably longer nowadays. All in all, it's worth a shot if you've got minor sound sensitivity as long as you're ok with the price tag and putting the things in regularly.

The product does what it promise. I am not really sure how, since i don't feel great difference in sound when i take them off, but it's undeniable that i am more calm and noise is not so annoying like before.
They stay in place all day (but sometimes i felt some itch, especially the first day).
The 10 db reduction is exactly what I need in a crowded restaurant.
The only bummer is the way the product is cheaping packaged: it came in a paper bag, it's not a nice paper box you can store if you want to put the flare away for some reason.
Also it is a product that has very little parts and i want to be able to take the - 10db filter with me to use it when i need it. A quality little box is required but i don't think the boxes offered on the website are ok either: too big! the only small is the little capsule but the way it opens is not the best for the little filters: you have to pour it on your hand or a table and in doing so it is very likely that you will drop one of them or they will roll over.
The pouch provided is simply useless to keep very little things like the - 10db filter alones: it doesn't seal perfectly.
The terrible presentation and, more important, the bad and expensive boxes are what made me choose to put a 4 stars review.

These little pieces of magic help when I'm out, especially in a busy restaurant as I have Misophonia. They minimise noise really well & I am able to enjoy an evening out without getting stressed. The normal, everyday clunking of cutlery on plates, loud talking, staff bashing glass bottles together etc, (you get the idea!) but I'm still able to clearly hear the people I'm with & because they are supple, they don't make my tinnitus worse, as other products have done previously.
I cannot recommend them highly enough. Treat yourself, you won't be disappointed.
