Combine — play both at onceswitching tabs doesn't stop the other engine, it just keeps running quietly — this decides whether it's actually audible
Binaural needs headphones — each ear hears a different pitch. Isochronic pulses one tone and works fine over speakers.
Session Arc — glides both engines between bands together, instead of holding one

Use headphones — the effect depends on each ear hearing a slightly different pitch. Sound continues even if you switch tabs.
Nothing here is medical advice; stop if you feel discomfort.
