Schumann Claims and Consumer Audio

The Schumann resonance is a real Earth–ionosphere story around 7.8 Hz. Your headphones are not the planet.
Spectra of the cavity exist. Linking that peak to a binaural beat of 7.83 Hz is numerology with a decimal point. Different physical domains sharing a number.
Consumer “Schumann tuners” sell a feeling of being plugged into Earth. Fine as poetry. Not fine as geophysics.
If 7.83 Hz feels like a good theta-adjacent sit, use it as a beat target and say that. Leave the ionosphere out of the checkout.
Schumann Claims and Consumer Audio is a door, not a clinic. Skeptical framing. Sit with a true-stereo pair if the hour still wants one. Skip it if silence is the better instrument tonight.
