What is this tool?

This tool plays a short test sound in your browser and lets you isolate the left or right channel, so you can quickly confirm both speakers or both sides of your headphones are producing audio.

How to use it

Press Play to start the test tone, then use the Left, Both, or Right buttons to move the audio to one channel at a time and listen for sound from each side.
  1. Click the Play button to start the test audio.
  2. Click Left to send audio only to the left channel.
  3. Click Both to play audio on both channels.
  4. Click Right to send audio only to the right channel.
  5. Click Play again to pause the test at any time.

Example

Example: after pressing Play, click Left -- you should only hear sound from your left speaker or earbud; click Right to confirm the opposite side.

How it works

The page uses the browser's built-in HTML5 `

Common use cases

  • Checking new headphones or earbuds for a dead channel.
  • Verifying a laptop's or monitor's built-in speakers after a repair.
  • Diagnosing a "my left ear can't hear anything" complaint.
  • Testing audio output after changing sound settings or drivers.

Benefits

Instant, free, no software install, and runs in a browser on devices with audio output.

Limitations

This test only verifies that your browser can play audio and route it to a channel; it cannot diagnose hardware faults inside a speaker, detect distortion, or measure precise audio quality or frequency response.

Privacy & your data

Audio playback happens locally through your browser and device. No microphone access is used and no data is sent to or stored on the A2Z Tools server.

Frequently asked questions

I don't hear anything when I press Play -- what's wrong?
Check that your device volume is turned up, the correct audio output is selected in your system settings, and that your browser has permission to play audio (some browsers block autoplay until you interact with the page).
Can this test detect a damaged speaker?
It can help you notice that one side is silent or much quieter than the other, but it cannot diagnose the exact hardware cause -- for that, a technician or manufacturer support may be needed.
Does this tool need microphone access?
No. This tool only plays audio; it does not use your microphone or request microphone permission.
Is this test free to use?
Yes, it is free with no signup or usage limit.
