The MOONDROP FreeDSP is a USB-C upgrade cable for 0.78mm 2-pin IEMs with built-in DSP, a fully balanced output and a three-button mic remote, rated by Moondrop at distortion as low as 0.0008% and a 120dB dynamic range. It suits phone and laptop users who want to plug their IEMs straight into USB-C and tune them in the MOONDROP Link app.
Who the MOONDROP FreeDSP is for
Phone and laptop listening: The USB-C plug works driver-free with phones, tablets and computers, so 2-pin IEMs connect without a separate dongle.
Tuning your IEMs: MOONDROP Link 2.0 lets you switch tuning presets, build a parametric EQ and download configurations shared by Moondrop and other users.
Calls and controls: A three-button in-line module with a mic handles volume, play/pause and calls, and its wiring is kept separate from the audio lines.
Clean, balanced output: Moondrop rates the fully balanced output at distortion as low as 0.0008% with a 120dB dynamic range.
Skip it if: your IEMs use MMCX or another connector — this cable ends in 0.78mm 2-pin plugs — or your device lacks a USB-C port; earphones are not included.
