Moondrop CHU II DSP USB-C In-Ear Monitors

Moondrop CHU II DSP are USB-C wired in-ear monitors with a 10mm dynamic driver, aluminum-magnesium diaphragm, alloy shell and switchable DSP bass presets for adaptable, detail-focused listening.

The CHU II DSP from Moondrop combines a high-rigidity aluminum-magnesium composite diaphragm, a precision brass nozzle and a cast metal cavity to deliver clear treble and controlled bass from a USB-C connection. Built with a 10mm dynamic driver and low distortion, these Type-C earphones include an interchangeable 0.78mm two-pin cable system, a leather case, multiple ear-tip sizes and an app-driven DSP for three selectable bass profiles. The package targets listeners who want refined acoustic detail and flexible tuning without adding an external DAC or adapter.

How do these earphones shape sound compared with typical wired IEMs?

The CHU II DSP uses an aluminum-magnesium dome composite diaphragm and a brass CNC nozzle to extend treble bandwidth and improve transient response, while the cast alloy cavity adds structural rigidity to reduce unwanted resonance. A built-in DSP provides three bass presets to tailor low-frequency response without changing hardware.

• 10mm high-performance dynamic driver for balanced midrange and impact.
• Al-Mg alloy diaphragm for clearer highs and faster detail retrieval.
• Brass nozzle and alloy cavity for consistent timbre and reduced coloration.
• Three DSP bass modes adjustable via the Moondrop Link app.

What connectivity and compatibility can I expect from the USB-C design?

The CHU II DSP plugs directly into USB-C ports, delivering digital-to-analog conversion and DSP processing without needing a separate adapter for compatible devices. The included cable is removable via a 0.78mm two-pin connector, so you can swap cables or use Bluetooth neckbands and TWS ear-hook cables that adopt the same standard.

• USB-C plug for direct connection to modern phones, tablets and laptops with Type-C audio support.
• Interchangeable 0.78mm-2pin cable lets you replace or upgrade the wiring.
• Works with Moondrop Link app to switch DSP bass presets and fine-tune sound.
• Includes multiple ear-tip sizes for a secure seal and improved isolation.

How durable and portable are the CHU II DSP earphones?

Moondrop uses alloy casting for the main cavity and a corrosion-resistant paint layer to protect the metal shell, providing long-term durability and a premium finish. The earphones ship with a leather case and a replaceable cable system so you can store and maintain them for regular travel or daily carry.

• ZN alloy cavity with protective paint for corrosion resistance and resilience.
• Brass CNC nozzle with precise machining reduces wear and maintains acoustic geometry.
• Supplied leather case and wearing card for organized transport and protection.
• Interchangeable cable reduces single-point failure risk and extends service life.

What technical specifications define their performance?

These in-ear monitors cover a wide frequency range and maintain low distortion at common listening levels, making them suitable for both casual listening and critical playback. The IEC effective response centers around the audible band, while the extended full-range spec indicates the driver’s capability beyond that band.

• Frequency response: 15 Hz–38 kHz (full), effective 20 Hz–20 kHz (IEC60318-4, -3 dB).
• Driver: 10mm high-performance dynamic driver with Al-Mg alloy composite diaphragm.
• THD: ≤0.5% at 1 kHz, 94 dB SPL—low distortion for clean playback.
• Connectors: USB-C plug; 0.78mm 2-pin removable cable jack.

Who is this for? The Moondrop CHU II DSP suits listeners who want a refined wired listening experience from USB-C devices: audio enthusiasts who value treble clarity and tunable bass, commuters and travelers who need a durable, portable IEM with interchangeable cabling, and creators who want low distortion and wide frequency capability without adding external DACs. If you need Bluetooth-only wireless convenience or an exclusively neutral studio reference, consider whether a different model better matches those priorities.
