Solfeggio Frequencies
Solfeggio frequencies refer to specific tones of sound that are believed to promote body and mind health. We suggest playing them at low volume to experience their benefits.

No headphones required.
Binaural Beats
Binaural beats influence the brain in various ways. The effect of each brainwave depends on its frequency. Stereo headphones are required to hear them due to their oscillating nature. Brainwave sounds are beneficial when not conflicting with each other, for that reason only one can be selected at a time.
Requires headphones.
Isochronic Tones
Isochronic tones influence the brain in various ways. The effect of each brainwave depends on its frequency. No headphones are required, but the sound they produce is very subtle. Brainwave sounds are beneficial when not conflicting with each other, for that reason only one can be selected at a time.
