Audio Latency Test
Tap when you see the flash or hear the beep
Before You Start
- 1Connect your Bluetooth headphones or earbuds to this device
- 2Set volume to a comfortable listening level
- 3Find a quiet environment with no distractions
How This Test Works
- Step 1 - Calibration:Tap when screen flashes yellow (measures your reaction time)
- Step 2 - Audio Test:Tap when you hear the beep sound
- Result:We subtract your reaction time to get pure audio delay
How It Works
Three simple phases to accurately measure your Bluetooth audio delay
Calibrate Reaction Time
The screen flashes yellow. Tap as fast as you can when you see it. This measures your personal reaction speed.
Listen & Tap
A beep plays through your headphones. Tap immediately when you hear it. This measures audio + reaction time.
Get Your Results
We subtract your reaction time from audio time to reveal your true Bluetooth latency in milliseconds.
Pro tip: Use a quiet room, stay focused, and tap as fast as possible. You can also press Space instead of clicking. Run the test 2-3 times for the most reliable results.
Frequently Asked Questions
What is audio latency?
It is the delay between when your device plays a sound and when you actually hear it. Bluetooth adds extra processing time compared to wired headphones, usually 40-200ms.
Why does latency matter for gaming?
In fast-paced games, you rely on sound cues like footsteps or gunshots. If you hear them late, you react late. Under 40ms is ideal for competitive play.
What does "Accuracy" mean?
It shows how consistent your reaction times were. Higher is better. If it is low, try again in a quiet room with fewer distractions.
How can I reduce Bluetooth latency?
- Enable "Gaming Mode" or "Low Latency Mode" in your headphone app
- Use aptX Low Latency or aptX Adaptive if your device supports it
- Keep your headphones charged
- Stay close to your audio source
- For competitive gaming, wired headphones are still the safest bet
How accurate is this test?
It measures relative latency by comparing your visual reaction time to your audio reaction time. It is not lab-grade, but it gives a solid estimate of your headphone delay. Run it 2-3 times and compare results.
What the numbers mean
- Under 40ms: Great for competitive gaming and music production
- 40-80ms: Fine for casual gaming and video calls
- 80-150ms: Okay for videos and music, but gaming may feel off
- Over 150ms: You will notice the delay in most activities
How the test works
The test runs in two phases. First, you tap when the screen flashes yellow. This measures your baseline reaction time. Then, you tap when you hear a beep through your headphones. The difference between the two gives a rough estimate of your audio delay, minus your personal reaction speed.
We run multiple rounds and drop obvious outliers so one slow tap does not throw off your whole result.
Who this test helps
Gamers want to know if their Bluetooth gear will hold them back in competitive play. Video editors and musicians need to know if monitoring through wireless headphones will throw off their timing. And if you watch a lot of movies, high latency can make lip-sync feel slightly off. This test gives you a quick way to check.
