Moondrop Chu II DSP Căști auricular

USB-C In-Ear Monitor with Built-In DAC and App-Based Tuning

The Moondrop Chu II DSP is a single-driver in-ear monitor that pairs the Chu II acoustic platform with an integrated USB-C DAC, letting listeners plug straight into modern phones and laptops without a dongle. A 10mm dynamic driver sits inside a ZN alloy cavity, paired with an aluminum-magnesium alloy composite diaphragm. The Moondrop Chu II DSP is the right choice for anyone who wants a clean, VDSF-tuned sound signature and a single-cable solution for devices that have dropped the 3.5mm jack.

What Sets the Chu II DSP Apart

What sets this model apart is the combination of a CNC-machined brass acoustic nozzle with a replaceable acoustic filter and an integrated DSP chip that processes the digital USB-C signal before it reaches the driver. The MOONDROP Link 2.0 app exposes three switchable tuning profiles and interactive online DSP tuning, so the sound can be reshaped without touching the hardware.

Driver, Tuning, and Connectivity Specifications

The spec sheet balances audiophile tuning targets with everyday usability. The 18Ω impedance and 119dB/Vrms sensitivity keep power demands low, so the integrated DAC drives the driver comfortably without external amplification.

• Driver: 10mm dynamic driver with aluminum-magnesium alloy composite diaphragm
• Frequency Response: 15Hz - 38kHz (effective 20Hz - 20kHz per IEC60318-4, -3dB)
• Impedance: 18Ω ± 15% (@1kHz) — easy to drive from any USB-C source
• Sensitivity: 119dB/Vrms (@1kHz)
• THD: ≤ 0.5% (@1kHz, 94dB) — distortion stays inaudible at normal listening levels
• Connectivity: USB-C plug with integrated DAC, 0.78mm 2-pin detachable cable

Built for Phone-First Listeners, Beginners, and Tinkerers

The Chu II DSP suits listeners who want a clean, VDSF-aligned sound out of the box with room to experiment. It connects directly to phones, tablets and laptops with a USB-C port, and the MOONDROP Link 2.0 app lets users switch between the three tuning profiles or build and share their own. The CNC-machined brass nozzle with replaceable filters and the standard 0.78mm 2-pin connectors keep the IEM serviceable and upgradeable over time.

MOONDROP and the Chu Lineage

MOONDROP tunes its in-ear monitors around the VDSF target response curve. The Chu line continues that philosophy at the entry level, and the Chu II DSP extends it with USB-C convenience and software-driven tuning for the dongle-free generation.
