It features a CS43198 DAC chip paired with a DSP processor, allowing optimization of frequency response and sound signature according to listening preferences. Capable of handling audio streams up to PCM 32bit 768kHz and DSD256, it ensures precise conversion and faithful reproduction with a 127dB dynamic range and ultra-low distortion (0.00017% THD+N).
Equipped with a USB-C to 3.5mm female jack connection, it functions as an active digital audio cable for smartphones, tablets, and computers. It delivers a maximum output power of 2x80mW at 16Ω, allowing demanding earphones to perform at their full potential. Ideal for mobile or portable audiophile use, the FreeDSP Mini unlocks the full capability of your IEMs while providing advanced sound control.
The FreeDSP Mini’s CS43198 DAC supports PCM up to 32bit 768kHz and DSD256. In addition, a free DSP interface is accessible via the Moondrop Android application, allowing users to adjust filter type, frequency points, gain, and Q values. A comprehensive headphone frequency response database is also available as a reference during tuning. DSP adjustment can also be performed via the web interface, offering a more professional, complete, and precise environment than the mobile application.
The Moondrop Web and Android applications are updated simultaneously, eliminating the need for manual adjustments. Users can simply select or upload original frequency curves and target responses for one-click application, enabling deeper sound customization.

Thanks to its high-performance decoding chip and LDO-based design, the FreeDSP Mini achieves a dynamic range of up to 127dB and total harmonic distortion as low as 0.00017%, with a maximum output power of 2x80mW at 16Ω.

Featuring a USB-C interface, the FreeDSP Mini connects easily to smartphones, computers, and tablets. It delivers superior sound quality compared to standard USB-C earphones while eliminating latency and signal degradation.
