Speaker & Headphone Test

Play a short test tone to check whether sound comes through your speakers or headphones, including left and right stereo channels.

Speaker result & next steps

Test your device above, then review what the browser actually confirmed. A connected device is not the same as a certified working device.

Ready for testing

No result yet. Start the test above.

  • Choose left, right or both and confirm you can actually hear the tone.
  • If silent, check output device, hardware mute and operating-system volume.
  • Browser audio generation cannot automatically confirm the physical speaker works.

How do I test laptop speakers or headphones?

Quick answer

Turn your volume down first, then play a short test tone. Choose left and right channel tests to check which side you hear. The website can play sound, but only you can confirm audibility and whether each channel sounds correct.

How to run this test

  1. Set your device volume to a comfortable, low level.
  2. Connect the headphones or speakers you want to test.
  3. Play a test tone using the left channel, then the right.
  4. Confirm whether sound is audible in the expected ear or speaker.
  5. Adjust your system output device if the sound comes from the wrong hardware.

Understanding your result

✓ What a good result looks like

You can hear the test tones clearly and the left/right channels match your expectations.

! If something does not work

Silence can result from muting, wrong output selection or a disconnected device. A browser cannot independently detect whether you heard the tone.

Troubleshooting common problems

No sound from either speaker

Check browser-tab mute, master volume, connected cables and the operating system’s active output device.

Only one side plays

Inspect headphone balance settings, connectors, damaged cables and whether mono audio is enabled.

Sound is distorted

Lower the volume and compare with another headset or speaker to isolate a hardware problem.

What this browser test cannot prove: Speaker tests are subjective: the browser generates a tone but cannot measure your actual speaker output, frequency response or acoustic quality.

Frequently asked questions

Can a browser automatically detect a broken speaker?

Not reliably. A website can emit test audio; you must confirm whether you hear it and whether channels match.

How do I check left and right headphones?

Use the left and right channel controls while wearing headphones, listening for sound in the expected ear.

Why is the sound coming from another device?

Your operating system may be routing audio to Bluetooth headphones, a monitor or another output. Change the system output setting.

Is this a hearing test?

No. This is a basic speaker-output check and should not be used to assess hearing ability.
