Speaker and Headphone Test

Make sure your left and right channels are the right way round and that both speakers or earbuds work. Play beeps in the left channel only, the right channel only or both, or let them alternate automatically. Sound starts at a gentle level, and you can download a short stereo test file to check other devices.

Frequently Asked Questions

Left and right are swapped. What should I do?

Check that the headphones are worn the right way (look for L and R marks). For speakers, swap the cables or use your system’s balance setting.

I hear the left beeps in both ears. Why?

A mono setting may be active. On Windows look for “Mono audio” in accessibility settings; on iPhone and Mac, check “Mono Audio” in accessibility settings too.

Is the test loud?

No. It starts at 20% of full level and the slider stops at 80%. Still, start with your device volume low.

Does it need an internet connection?

Only to load the page. The tones are generated in your browser.
