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.
Community Sharing & Downloads
Built-in community support lets you upload and share your own tuning presets or download optimizations created by other users. Whether you’re a seasoned pro or a passionate enthusiast, you can correct timbral defects and tailor your playback to any style or scenario.
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.
Continuously Updated Frequency Library
The FreeDSP Pro comes with an extensive library of headphone response curves that you can use as starting points or targets. We’re constantly adding new curves, so your toolkit grows over time, keeping your tuning options fresh and up to date.
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.
Flagship Decoding Performance
Equipped with the CS43198 decoding chip and powered by precision LDO regulators, the FreeDSP Pro handles PCM up to 32-bit/384 kHz and DSD256. Enjoy reference-level HiFi quality with up to 127 dB dynamic range and total harmonic distortion as low as 0.00017%.
High-Output HiFi Sound
Delivering up to 80 mW per channel into demanding loads, the FreeDSP Pro ensures you’ll have plenty of headroom and clarity, whether you’re enjoying detailed classical recordings or pumping bass-heavy tracks.
Premium Silver-Alloy Litz Cable
The included custom Litz-structure single-crystal copper cable uses 20% silver-alloy solder for exceptional signal transmission and a naturally laid-back timbre—identical in build quality to Moondrop’s Atami upgrade cable.
