HeadphoneEQ

HeadphoneEQ applies scientifically-measured EQ corrections to your Mac's audio output, compensating for your headphones' frequency response deviations. The result: flatter, more accurate, more natural sound.

ZERO SETUP HeadphoneEQ captures system audio directly using CoreAudio — no virtual drivers, no configuration changes. Select your headphones, tap Start, and every app (Spotify, Apple Music, YouTube, Netflix) sounds better instantly.
