Good to know
The tone is generated in the browser, so nothing is downloaded. Start at a low volume, especially with headphones.
The sweep runs from 200 Hz to 8 kHz. What you hear also depends on your output device, so this is a channel and continuity check, not a calibrated measurement.

Questions
Left and right are swapped. What now?
Check how the headphones are worn and any audio balance setting in your system.
Why do I hear crackling in the sweep?
Distortion at some frequencies can mean a damaged driver or loose connection. Try another device to compare.
