The use of binaural beats may help reduce the time required to fall asleep and improve overall sleep quality, even in the absence of detectable brainwave entrainment.

Research on binaural beats presents a mixed picture. There are studies, such as the one mentioned by the creator or systematic reviews (e.g., Garcia-Argibay et al.), that suggest a positive effect on pre-sleep anxiety and sleep latency. However, the evidence remains limited by often small sample sizes and significant methodological variability. The idea that these sounds act without directly altering brainwaves is an interesting hypothesis that shifts the debate toward other mechanisms, such as cognitive relaxation or the placebo effect. While some research shows benefits for sleep quality, other studies report null results, which highlights a heterogeneity in individual responses. It is therefore reasonable to consider this tool as a potential low-risk aid, while acknowledging that science is far from definitive regarding the magnitude of its effects.
