SoundID Reference for Headphones and Apollo Monitor Correction Add-on Bundle

Sonarworks SoundID Reference for Headphones is a calibration utility that flattens the frequency response of your existing headphones, using profiles for over 500 models to emulate neutral-sounding studio monitors. The bundle adds Apollo Monitor Correction, letting you run that calibration directly on Universal Audio Apollo X Gen 1 and Gen 2 interfaces. The result is consistent, accurate monitoring whether you mix on headphones, speakers, or both, so your tracks translate reliably to phones, laptops, and earbuds. It suits hobby producers and engineers who want more confidence in their monitoring decisions without upgrading their entire setup. Use the plugin in your DAW or the Systemwide app to apply correction across your system, and switch between projects or locations knowing your reference sound stays flat and dependable.
