Why do I need headphones? A meaningful hearing check needs headphones; the iPhone speaker can't deliver calibrated tones. AirPods give calibrated results; other headphones show a relative trend.
Are my results a diagnosis? No. Tone is for personal awareness only. Consult an audiologist for an actual diagnosis.
