Earbud Checker: Latency & L/R

Earbud Checker tests your earphones and headphones in minutes. Step-by-step picture guides show exactly what to do, so anyone can run every test.

MEASURE LATENCY (AUDIO LAG) The app plays a short click and listens for it with your phone's own microphone, then shows how many milliseconds your earbuds add. No stopwatch, no guessing. - Works with Bluetooth, wired and USB earphones - Tells you if the delay is fine for video, music or games - Use the number for in-game audio offset settings - iOS also shows the latency the system reports, next to the measured value

FREE TESTS - Left / Right: a voice says "Left" and "Right" in each ear - Volume balance: find out if one side is quieter - Phase (polarity): spot reversed wiring - Frequency range: how low and how high you can hear with these earphones - Rattle & distortion: deep bass sweeps reveal buzzing - Earphone mic: record and play back, and see which mic was actually used - Full checkup: run the basic tests in order and get one result card

EXTRA FEATURES Watch one ad to use them for 24 hours, or unlock them forever with a one-time purchase (which also removes ads). - Precise latency: 10 rounds with the spread - History and comparison between your earphones - Export the result card as an image - Sound direction test

GOOD TO KNOW - This is not a medical device and does not test your hearing. - Recordings and measurements stay on your device. You can optionally share a latency result anonymously to help build typical figures per model. - The same earphones can measure differently with another phone, codec or game mode.
