Delay test
Five clicks go out of your speakers and back into your mic. The time between is your device's round-trip delay in this browser.
- Use speakers, or hold one earcup of your headset against its mic.
- Set the volume so a click is clearly audible, and keep the room quiet for ten seconds.
- Press Start and allow the mic. Don't talk until it finishes.
Not measured yet.
The mic is used only during the test, inside this tab. Nothing is recorded or uploaded.
What the number means
It is the whole round trip on this device: the browser's output buffer, the sound card or Bluetooth link, the air between speaker and mic, and the input buffer. It is not your internet ping and not the delay your friends hear in a call, which adds the network and the call app.
- Wired headsets and USB mics usually measure lowest. If you hear yourself through software (this site's mic test, Windows' Listen to this device), you hear about this much delay.
- Bluetooth headphones add a lot on the output side, and a Bluetooth headset's mic often switches the whole headset to a lower-quality call mode. For game chat a wired or 2.4 GHz dongle connection is the better path.
- To hear yourself with no delay, use a mic's own headphone jack or a headset's sidetone: they skip the computer entirely. How to hear yourself without delay
If no click is heard, raise the volume, move the mic closer to the speaker, or check in the mic test that the browser hears your mic at all.
