Free Online Speaker & Headphone Test
Check left and right channels on speakers, headphones or a headset. Run a stereo sound test before your next call, game or recording.
No sign-up or microphone access. Sound starts on click.
Check your audio output
Start with low device volume. Stop if the tone feels uncomfortable; do not raise volume to force a result.
Relative software level, not a measured listening volume. Your device volume still applies.
Ready. Lower your device volume before playing a test.
Sound follows your browser’s current output. Choose speakers or headphones in your device settings. Single tests stop after 2 seconds; the sequence stops after 6 seconds.
How to test speakers or headphones online
Choose the output you want to check
Connect your headphones, headset or speakers and select them as the output in your system’s sound settings. A Bluetooth device may appear as more than one audio mode. Confirm that you selected the intended device, not a monitor or laptop speaker.
Lower the volume and play the left channel
Wear headphones the correct way around, with L on your left ear and R on your right. Press Play left channel. With a stereo setup, the tone should come from the left side. On speakers, sit where you can distinguish the two outputs.
Compare the right channel and both channels
Play the right-channel test, then both channels at the same settings. The two-second tones use the same signal level. Judge whether both sides are audible; this tool cannot measure their physical loudness for you.
Run a stereo sequence
The six-second sequence plays left, then right, then both. The highlighted labels follow the intended channels. If the sound does not match them, check routing, mono audio, balance and connections.
Check the microphone separately
A successful headphone audio test confirms playback only. For a headset audio test before a call, also record and listen to your headset microphone in the input tester.
What does your headset check tell you?
Left and right match the labels
The browser’s output reaches the expected stereo sides. This is a useful routing check, not a complete headphone quality assessment. Compare normal speech or music afterward at a comfortable level.
The channels sound reversed
Check headphone orientation, speaker wiring and adapter routing. Disable channel-swapping or spatial processing if you use it, then retest. The browser sends channel one as left and channel two as right.
Only one side is audible
Review system balance and fully seat the connector. Compare another cable, port or device where practical. A mono device may not reproduce a stereo test as two separate sides.
Both sides play during every test
Check whether mono audio, an adapter or virtual-surround processing combines the channels. With speakers, some sound naturally reaches both ears; use physical speaker position rather than expecting ear isolation.
Headphone mic test: check input as well as output
A headset has separate playback and recording paths. You can hear a call clearly while the other person receives silence from your microphone. After this headset tester, select the headset input in the microphone tool, allow access, record a short sentence and listen back.
Check the headset’s physical mute button and your meeting app’s input choice. Choosing headphones as your system output does not necessarily select their microphone for every app.
Start headset microphone testConnect the right port or adapter
A combined 3.5 mm headset plug carries different signals from a headphone-only connection. Some computers need a compatible splitter, while USB headsets use their own audio interface. A working output does not prove the microphone connection is supported.
Read the PC and Mac microphone setup guide for connections and permissions, or the microphone testing hub for recording checks.
No sound or distorted playback? Try these checks
- Check device volume, headset controls, browser-tab mute and the chosen output. At a signal level of 0%, this tool intentionally produces silence.
- Play a familiar audio clip in another app. If that is also silent, investigate the system output or connection before changing browser settings.
- Disconnect and reconnect Bluetooth equipment, then reselect its output. Wireless call modes can change playback quality.
- For crackling or distortion, reduce volume and compare another cable or port. Disable extra processing temporarily if it changes channel routing.
- Try another supported browser if a test cannot start. Sound begins only after a button press; some browsers or managed devices restrict playback.
On Windows or Mac, use the system sound output selector. On a phone or tablet, check the active audio route and media volume. This page cannot switch your hardware output automatically.
What this sound test can and cannot measure
The tool generates short 440 Hz tones in your browser. It checks basic playback and channel routing, and requests no microphone permission. It does not record your environment or listen to the result. Page files and fonts still load over the network.
This is not a hearing test, frequency sweep, calibrated loudness measurement, surround-sound certification or latency test. The browser cannot tell whether you heard a tone or assign a reliable quality score. System mono settings, audio enhancements, speakers, adapters and wireless modes can change what reaches your ears.
Keep the listening level comfortable and stop if necessary. Do not use a missing tone as a reason to keep increasing volume. See the privacy policy and audio help for related information.
Speaker, headphone and headset test questions
Can I test a headset microphone here?
This page checks playback through your speakers or headphones. Use the linked microphone tester to record and listen to your headset mic. Output and microphone input are separate checks.
Why do I hear both ears during a left-channel test?
Your system may have mono audio enabled, a connection may combine channels, or audio processing may alter the signal. Check accessibility audio settings, balance, adapters and any virtual-surround processing before repeating the test.
Why is there no sound?
Check the selected output, device and tab mute, system volume and the connection. Click a test button to start playback; this page does not autoplay. Reconnect Bluetooth equipment and reselect it as an output if needed.
Can this test prove that my headphones are faulty?
No. Silence or imbalance can come from output settings, cables, adapters or software. Compare a known audio clip and another device before concluding that hardware is damaged.
Does the tool measure frequency response or hearing?
No. The short 440 Hz tones check channel routing and basic playback. They are not a frequency-response, loudness, latency or hearing measurement. There is no automatic quality score.
Do I need an account or microphone permission?
No account, installation or microphone permission is required for this playback test. Test tones are generated in the browser. The separate microphone tester asks for access only after you start it.
