What is 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.

4,500+ HEADPHONE PRESETS Powered by the AutoEQ database with measurements from trusted sources:

  • oratory1990 (parametric EQ)
  • crinacle
  • rtings
  • innerfidelity

Supports Sony, Sennheiser, AKG, Beyerdynamic, HiFiMAN, Audio-Technica, Apple AirPods, and hundreds more.

AUDIOPHILE-GRADE PROCESSING

  • 64-bit internal precision (Double), Float only at final output
  • TPDF dithering with 2nd-order noise shaping
  • Adaptive Q factors based on frequency spacing
  • Auto-gain compensation prevents clipping
  • DC blocking filter removes subsonic artifacts
  • Smooth tanh-based limiter — no hard clipping, ever

30-BAND CUSTOM EQ Don't see your headphones? Create your own EQ curve with 30 bands of precise parametric control from 20Hz to 16kHz.

ADJUSTABLE PREAMP Fine-tune overall volume from -12 to +12 dB. Auto-gain info shows exactly how much compensation was applied.

LIGHTWEIGHT Native Swift app, under 1MB, lives in your menu bar, uses less than 1% CPU.

PRIVATE No account required. No telemetry. No data collection. Preset data is cached locally after first download.
