HeadphoneEQ

Make any headphones sound their best on Mac

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.
