What to look for
If the sides sound reversed, check headphone orientation and the system’s output settings.
Web Audio generates tones for listening checks. Start at low volume and stop if uncomfortable. Audibility depends on the output device and hearing; these tools are not medical hearing tests or calibrated frequency-response measurements.
