Moondrop Quark2 In-Ear-hovedtelefoner

USB-C In-Ear Monitors with Built-In DAC and DSP

The Moondrop Quark2 is a wired USB-C in-ear monitor aimed at listeners who want high-fidelity sound straight from a phone, tablet, or laptop without buying a separate DAC. A built-in audio SOC chip handles 32-bit/384 kHz hardware decoding and runs an interactive DSP, so the earphones deliver a clean, low-distortion signal the moment they are plugged in. Closed front cavity acoustics keep external noise out and bass response tight for commuting, office work, and casual listening at home.

What Sets This Model Apart in the Entry-Level IEM Category

Most budget in-ear monitors rely on the host device's built-in DAC, but this one carries its own audio SOC chip with 32-bit/384 kHz hardware decoding and a graphical online interactive DSP. The 7.8 mm micro-dynamic driver pairs an LCP dome with a flexible suspension diaphragm, an N52 magnetic circuit, and a lightweight CCAW drive coil for fast transient response. A dual acoustic filter design tames ultra-high-frequency resonance, eliminating the harshness often found in entry-level Hi-Fi earphones.

Technical Specifications — Driver, Sound, and Connectivity

Engineered around a single micro-dynamic driver tuned to the VDSF Target Response, this model uses a closed front cavity that delivers a pure-pressure soundstage and punchy bass. Full-link nonlinear distortion stays below 0.05% at 1 kHz, and the frequency response covers the full 20 Hz – 20 kHz audible range within ±3 dB per IEC 60318-4. Wired USB-C transmission eliminates wireless latency for Hi-Res music listening, video calls, and rhythm-based games.

• Driver: 7.8 mm micro-dynamic driver with LCP dome composite flexible suspension diaphragm — N52 magnetic circuit and lightweight CCAW coil
• Frequency Response: 20 Hz – 20 kHz (IEC 60318-4, ±3 dB)
• THD: ≤0.05% at 1 kHz — full-link nonlinear distortion kept low by the audio SOC chip
• Connector: USB-C (UAC 2.0 protocol) — compatible with Android, iOS, iPadOS, Mac, and PC
• Cable Length: 1.2 m

Who This USB-C IEM Is For

These USB-C in-ear monitors are the right choice for listeners who want clean, balanced sound from a phone, tablet, or laptop without buying a separate DAC. Students, commuters, and office workers benefit from the closed front cavity's strong sound isolation, while mobile gamers and content creators will appreciate the zero-latency wired connection, the three-button inline remote, and the HD microphone for clear voice capture.
