How it works and what the result means
Peaking filters centered at 60, 250, 1000, 4000 and 12000 Hz change digital playback gain. Output is reduced to leave headroom for boosts.
Reading the result
The controls change digital playback through peaking filters. A louder result can seem better even when the tonal change is not useful.
What to check next
Reduce boosts if playback becomes harsh or distorted. Leave headroom and stop before changing headphones.
Your file is not uploaded. This playground does not install a system-wide equalizer or measure the physical response of your headphones.
Frequently asked questions
Is the EQ applied system-wide?
No. It affects the local audio element in this page. It neither uploads the selected file nor installs a permanent equalizer.
How do I start the Headphone EQ Playground?
Choose a local audio file, enable EQ and play the file. Move the five frequency-band sliders.
Does this tool require a download or an account?
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Why can two attempts give different results?
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
