Moondrop FreeDSP Pro / Free DSP Pro Upgrade Cable For IEM Earphone With CS43198 Chip & DSP Type C

Customizable Tuning Interface
Through the Moondrop App, you can adjust filter types, frequency points, gain, and Q-values with a user-friendly professional tuning interface. A comprehensive headphone frequency-response database makes it easy to reference original or target curves as you fine-tune your sound.


Web-Based Tuning Compatibility
If your device isn’t compatible with the mobile app, the online “Tuning Community” on our website offers the same professional, comprehensive, and precise interface. Seamless interoperability between your account, the web database, and the mobile app makes tuning flexible and convenient.


One-Click EQ Presets
For a quick setup, choose any original and target response curve in the Moondrop App or on the web for one-button EQ. This streamlined approach lets you explore new sounds without the hassle of manual debugging.
