HeadphoneEQ is a lightweight macOS menu bar app that applies scientifically measured
EQ corrections to your headphones in real-time.
Most headphones don't have a flat frequency response — some boost bass too much,
others have harsh treble or recessed mids. Acoustic researchers have measured
thousands of headphones and calculated the exact EQ needed to fix them. HeadphoneEQ
makes applying those corrections effortless.
