Will this work for everyone?

[Amaku]

I bought brain+ and hash, and I'm waiting until tonight to use it. Will i-doser work for everybody or are there some people that can't get it to work no matter what? If it doesn't work for me right away, will my brain be more susceptible to it the more I listen to it?

I congratulate you. You've just asked two very intelligent questions.

Nobody is "immune" to binaural beats, per se. Some people are resistant, but with practice, anyone can use them. Some doses (like brain+) help to improve you if you listen to them daily. Think of it more as a passive effect. Doses like hash will work eventually (and, given time and practice, even stronger than before). You just must practice if it doesn't work the first time.

Tl;dr -- It will work for everyone with practice and yes, you'll be more susceptible over time.

I tried to listen to many different doses for a long time but I never got any effects... What's wrong with me, my brain is too strong?

Yes, if you listen to a dose more than once, you become more susceptible to it

Seriously... Just keep trying. That's all it takes.
