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

Sonarworks SoundID Reference for Speakers & Headphones calibrates your studio monitors and headphones to deliver a flat, neutral reference sound, so your mixes translate reliably to phones, laptops, earbuds and car systems. The software includes over 500 headphone calibration profiles and corrects unwanted colouration across the frequency spectrum, helping you hear every detail and make confident mixing decisions. This bundle also includes the Apollo Monitor Correction Add-on, which integrates SoundID Reference directly into Universal Audio Apollo X Gen 1 and Gen 2 interfaces for seamless monitoring control. Ideal for hobby producers working in untreated or imperfect rooms, it lets you switch between speakers, headphones and rooms while maintaining consistent reference sound. Setup is straightforward: treat your room where possible, then calibrate. Whether you’re finishing tracks faster or collaborating remotely, SoundID Reference helps you stop second-guessing and trust what you hear.
