No. An isochronic tone is a single tone that switches on and off at a steady rate, so the rhythm is already in the sound itself. It works on any speaker, phone, or laptop. Headphones are optional.
Binaural beats send a different frequency to each ear and rely on the brain to combine them, which is why they need headphones. Isochronic tones pulse a single tone in the open air, so the rhythm is stronger and more distinct, and it plays through any speaker. Some people find the pulsing more noticeable and prefer it for focus; others prefer the smoother sound of binaural or monaural beats for rest.
Start in the Alpha range (8 to 13 Hz) for calm focus, Theta (4 to 8 Hz) for relaxation, or Delta (1 to 4 Hz) for winding down. Keep the volume low, and try 10 to 20 minute sessions first.
