Binaural beats require stereo headphones. Two slightly different tones — one per ear — create a perceived beat at the frequency difference. Without headphones, use Isochronic mode (works on speakers).
Contemplative audio for focus, relaxation, and meditation. Not a medical device. If you have epilepsy, a heart condition, or a pacemaker, consult your doctor before use.
Binaural beats require separate tones in each ear. Confirm your headphones are delivering true stereo.
