The calmer is about $25 it's basically an earplug with a hole in it. Some people have said it helps with tinnitus. 
Lame.  I bought them, they suck.  Save your $ or buy your girl some flowers.

The only thing they were halfway good at was providing ear protection while out in the world.  
One of them kept falling out of my ear and they’re confusing to place.

Overall though, avoid them.  
I tried them, primarily a high frequency attenuation. Did nothing for my tinnitus, but wasn't expecting anything there, honestly.

I would not recommend them.
