What is the L/R headphones test for?
The L/R (Left/Right) headphones test is a professional tool that allows you to verify the correct functioning of both audio channels of your headphones, earphones or headsets. This test is essential for detecting stereo audio problems, reversed channels or damaged headphones.
It uses Web Audio API technology to generate pure tones that play specifically on the left, right or both channels. You can adjust the frequency (from 20Hz to 20kHz) and volume to perform thorough tests.
Why test your headphones?
Verify Stereo Balance
Make sure both headphones sound with the same intensity
Detect Reversed Channels
Identify if L and R are swapped
Gaming and Music
Positional audio is critical in games and music production
Quality Control
Verify new headphones before using them

- •Use moderate volume to protect your hearing
- •If one channel doesn't sound, check connections before concluding they're damaged
- •Test in a quiet environment to better detect problems
