The claims are always full of confidence, "Binaural Beats do X", but I've never noticed even the slightest difference apart from sometimes an increase in boredom or frustration over the lack of anything "happening" with the sound.

Have anyone here experienced repeatable (if subjective) effects from listening, if so, how long did you listen for the effect to become noticeable ?

> Have anyone here experienced

Would you not rather know whether any randomized, double-blind, sham-controlled trial with meaningful group size had ever demonstrated a positive effect?

Sure, can you link me up ? :)

I cannot. To the best of my knowledge nothing like that exists. Everything I've seen of people "studying" it have cohorts of like 4 people or show no effect.
