I was wondering, does anyone of you have personal experience with them, or knows a specific youtube channel or site that offers good ones ? What is your view on them ?
I tried ones when I had a terrible headache, they helped me a bit, but they where too annoying and I turned them off after 5 minutes. I also tried another ones that were supposed to make me concentrated but I guess I just prefer listening to some music instead
I just found them on youtube, don't remember what channel it was.
