Binaural beats?

Any of you looked into binaural beats?
Had any success with them?
Examples?
I kind of skeptical because everyone wants to sell them but they seem interesting enough.

I listened to a couple for an hour, didn’t seem to do anything weird to me, though admittedly a calm and quiet place is hard to find in my house.

I listened to some at work once. I felt fine- not a natural state for me. Couldn’t tell you if that was the noises, or the power of suggestion though.

Imo some of it works indeed, it will kick some dopamin into the bloodstreams.
Though I think it’s nessesary to find that music that relates to you, else it will be without effect.
