The evidence is mixed. A 2023 systematic review examined 14 studies on binaural beats and brain entrainment: 5 found supportive evidence, 8 found contradictory evidence, and 1 was mixed. That's not a clear yes, and not a clear no.
This is why FMB builds its sessions on monaural and isochronic beats instead of binaural beats. The underlying mechanism is shared, but in two lab EEG studies monaural beats evoked larger brain responses than binaural beats (Schwarz & Taylor, 2005; Pratt et al., 2010). A larger brain response doesn't automatically mean a bigger effect on how you feel — that link is still being studied. We'd rather show you where the evidence is thin than borrow confidence from a form of entrainment we don't ship.
